General :: Unable To View Installed VM After Physical Machine Restart
Mar 15, 2011
I have a physical machine of CentOs-5.4 on which I had installed Xen Virtualization. I have created VMs on that machine using virt-install. After installing all the VMs i used command virt-manager to see all the installed VMs. But after I have restarted my physical machine I am unable to find installed VMs by virt-manager command. It only shows name of the machine and id a qemu and can't see any installed VMs.
i have sun Virtual box installed on my centos as my host os and centos as guest os.The ip on Sun virtual box virtual interface is10.0.2.15 and the ip on the physical machine is 192.168.1.11.when i try to ping the ip from my vps on centos to my physical machine it pings but it does't work when i try to ping my vps ip from my physical machine.Please recommend the route enteries i need to do in physical machine
I have just finished the upgrade of the latest version and I'm at the point of my system restating.
My system automatically tried to restart but on the restart I got the 'terminal' view. It stopped when asking for my username (it never normally asks for this before the grub menu) and then password. I didn't get any further than that.
I now have on my screen (still in the terminal view before the grub menu)
"name@name-desktop:...$ "
I'm on my phone now so I don't actually have the symbol for before the dollar sign but your know what it is. The raised S on a 90 degree angle.
I read once that you could use VMWare's converter to convert a physical machine into a virtual machine to run in VirtualBox. Can someone point me in the direction of a tutorial or just give me instructions on how to do this? I was very confused by the converter and how to get the image to work with virtualbox.
I need to deploy Windows Server 2008 R2 onto a server that is currently running Linux. Effectively, I want to restore a Windows disk image onto the Linux system hard disk.I don't have physical access to the machine, so I need to find a way to do everything remotely, using SSH (no KVM). And the Linux machine only has one hard disk - the one containing the OS. However, I might be able to create a partition in free space at the end of the hard disk to store the image (I might need some help with the Linux commands). Or perhaps the image file can be pulled via FTP.
I tried Acronis but was disappointed to find that it doesn't seem to allow me to overwrite the system partition (unlike the Windows version of Acronis, which is capable of doing this with a restart).
If I have only 1 physical WLAN interface, is there some hackery that can be done so that it can be a client of an existing access point and at the same time also act as an access point for other clients? I have an existing 802.11g ADSL router, and I'm going to be building an HTPC which will have 802.11n. My laptop also has 802.11n, but at the moment it only connects at 54Mbps because thats what the AP supports. I'd like to be able to have the HTPC be a client of my ADSL router, but have my laptop be a client of the HTPC, so copying files to it will be faster.
how to get the terminal displayed on my serverbox to show up in a terminal on my laptop. I have a minecraft server running on ubuntu server edition 10.04 on a headless server. I also have a monitor, but it's a big bulky CRT and my girlfriend doesn't like having a huge amount of stuff tucked behind our chair where the router is (wifi wasn't working right, nor is it stable).
Essentially, when I ssh into the box, it creates a new terminal for me to input things on. That's nice when I need to edit stuff in the background, but when I want to input commands on the server directly, there's no real way to do that without blindly typing on my keyboard on the box itself. Not to mention, I can't see anything if something goes wrong. A friend of mine mentioned the 'screen' command, and that sort of works I guess, but it still doesn't show the minecraft server output, nor let me input.
tl:dr;
is there a way to get a physical terminal output to display on a remote ssh terminal screen?
installed nagios on rhel 5.4_64 bit machine. now wants to monitor windows hosts using nagios,but not able to installed NSClient++-0.3.8-x64.msi error found while installing this package not supporting your processor type and 2203 error.
Is it possible to install Snavtclient, as i don't have much idea but i heard that i can view cameras online for AVTECH DVR once it is installed, i tried to download and install it through terminal but got this error.

I just installed slackware on my pc. The installation went fine (I think). When I am trying to turn the computer on, I am asked to type the "host login". As I can remember I didn't write any username, or password. But as it seems, I have to type this in to login. I tried with "root", then this comes up "root@host:^#" if this is right, what should I type here to get further...
Is there some way that I can use apache/iptables to serve both of my servers through the same basic domain? I'm not talking about VirtualHosts either, I don't believe ( despite the fact that's all I can find anything to read about on Google when searching for this ).
Anyway, the problem is that I have a TorrentFlux php torrent-client that I run so I can add stuff to the download when I'm not around. I don't want to put this on my regular webpage server because there's just not enough diskspace in that machine. On the other hand, I don't want to replace that server all-together because the other machine is my desktop and would not make a reliable host.
So my idea was that there could be some way to have the apache2 server on my dedicated server redirect a subdirectory in its webroot to the webroot of my desktop's TorrentFlux server, but over standard HTTP ports so that it is more like the server is serving up the content of my desktop server through its HTTP service, instead of simply redirecting.
The reason I want to do this is because so far I have to use the TorrentFlux server on a nonstandard port so my dedicated server can still host its own things on port 80, but I've been running into several situations where the browsers I want to use do not support the nonstandard port such as with some instances of IE or the browser on my BlackBerry.
Anyway, I'm not looking for a step by step or anything ( though it couldn't hurt ) but I just need some ideas on what I could search for to get some better ideas. There's probably some term for what I want to do I'm not even aware of that would help me greatly.
Runnining Ubuntu 7.04 and apache 2.2.4 along with shorewall 4.0 as my routing/firewall software.
I am encountering some problems regarding CentOS 5 and I am going to kindly ask your help in debugging further what is happening. I will give as much information as possible about the setup. Here we go. We use on one server of our servers, GOautodial, an inbound/outbound call center application, that it's installed on a CentOS 5.5 (Final).
# cat /etc/*release* cat: /etc/lsb-release.d: Is a directory CentOS release 5.5 (Final) GoAutoDial CE 2.0 # uname -a Linux xxxxx.com 2.6.18-194.8.1.el5.goPAE #1 SMP Fri Jul 30 05:30:57 EDT 2010 i686 i686 i386 GNU/Linux
I'm currently using ubuntu 9 for 4 years, then I decided to upgrade to ubuntu 10.4 then after wasting long hours of downloading updates and reinstall of new packages my computer request to restart the machine. after the boot sequence of grub my computer hangs up and no display at all, I tried to select different kernel but it won't help me at all what's the possible error after upgrading
I've been experimenting with Debian coming up with a system with suits my needs. I have done this and I'm wondering, "Do I have to start from scratch on my physical machine or can I convert an existing VDI to IMG and possibly port it to the physical machine?"
I'd like to access a samba/SSH server which itself is connected to a VPN Server, therefore acting as a VPN Client. As soon as the VPN Connection is established, samba and ssh connections to this VPN Client get a timeout. But not all of them.
To get a better understanding I made an overview. The first one is a general network overview, without any VPN Connection, the second one with the VPN Connection established.
Network Overview without VPN I can access the server in several ways: *From the router via ssh (router runs ipcop with busybox) *From the laptop via ssh (putty via Windows 7) *From the laptop via samba *From the internet via ssh (port forwarding to the ssh server)
Everything is working as it should.
Now the server that runs ssh and samba service connects to a VPN Server on the Internet, this is also working fine. Now it gets weird. The only samba/SSH connection that is still working is ssh directly from the router to the server. Everything else gets a timeout: *From the laptop via ssh (putty via Windows 7) *From the laptop via samba *From the internet via ssh (port forwarding to the ssh server) Network Overview with VPN active
Why is that? It seems from the little understanding I have of vpn and networking, that incoming packages (like samba request from the laptop) don't get send directly back over eth0 but over the vpn connection. This seems somewhat logic, BUT ssh from the router is still working. Why from the router and not from the laptop? I really can't get my head around it.
Configuration Overview
tldr; One Client acts as VPN Client and samba/SSH Server. As soon as the VPN Connection is established samba/SSH stop working, but only partially.
When I set up Twin View in the nVidia config tool (as either a regular user or as root), it only lasts until I log out and log back in (i.e. restart x) or until I restart the machine. In either case once I get to the log in splash screen again, it is only operating on one monitor, and when I log in I have to reconfigure in order to get Twin View back. How can I get the configuration to stay?
More info below:
I just installed opensuse 11.2 on an AMD 64 bit 3800. It has an nVidia GeForce 7600 GS card. I installed the nVidia driver no problem and can access the nVidia config app as a regular user or as root. Both access via KDE run level 5. That is, in a GUI desktop environment. I set up Twin View fine (it is kind of clunky process, but it does recognize my monitor resolutions fine) and click apply and I get the twin view I want. I clicked on save x config but all it does is bring up a file save dialog with a 'browse' button. Isn't this supposed to automatically know where the X config file is and update it? If it isn't, what file am I supposed to look for to save over? I looked in /etc/X11 and only found the following files:
I had linux installed on dell latitude d600, I did fdisk and deleted the OS so I can install Xp. When I try to boot from the Window xp cd , I get LINUX grub command line . " grub>" and can't do anything.I need window installed ASAP for a class that I am taking .
I have been learning Debian by using a virtual machine. After fine-tuning my installation procedure, I decided to copy that installation to my physical system. The hard drive already has another Linux based system installed. I plan to dual boot.After copying files I updated fstab and menu.lst.The partition scheme between the virtual and physical environments are similar, but the partitions are not mapped exactly the same.Thus the Debian system on the physical hard drive fails to boot simply because the initrd is created for the root partition location on the virtual machine. The initrd created in the virtual machine is looking for the root file system on /dev/hda1 whereas on my physical drive the new location is /dev/sda7.How can I rebuild the initrd on the physical system? I started to use the installation DVD in rescue mode, but I did not get too far.
I want to be able to add a physical drive to an existing filesystem, and PRESTO! That filesystem has more storage and/or redundancy. When one of the physical drives eventually fail, no problem, Ive lost some redundancy, I just have to install a new drive before another one fails.Lets assume I have 4 physical drives.*What Is This Configuration? *[URL]...But I am unclear how to get a logical volume that is mirrored and linear.
The last time I tried software RAID 1 (dm-x) under lvm, it was very fragile. Systemd could not start it,and then an update to mdadm put a stake through its heart. So I know that does not work.
When I installed Ubuntu, I created an 52 gb encrypted partition which shows up in the disk utility, and in the window that opens when I click on the "home folder" icon. I get my normal windows partition, and under that the 52 GB LVM2 partition. But when I try to access it, I get this error.
Unable to mount 52 GB LVM2 Physical Volume - not a mountable file system
This is what fdisk -l shows
Device Boot Start End Blocks Id System /dev/sda1 * 1 52 409600 27 Unknown Partition 1 does not end on cylinder boundary. /dev/sda2 52 30452 244193280 7 HPFS/NTFS
[Code]....
How can I fix this, and be able to access that 52gb partition? This is only my second day that I work with Ubuntu, so If more information is needed then let me know
I'm trying to use traceroute to view hop count between my machine and a specified external host but no matter what I give to it, it provides me the same output:
[Code]...
What am I doing wrong? Should I be disabling DNS caching? Is there a property I haven't set correctly? Just a small FYI, but I dual boot this computer with Win7 and it's tracert works fine. UPDATE: I also ran the command from a different network and it worked fine. I'm assuming I need a port forward then?
I have an apache server running on my ubuntu machine. I can view them using my local ip (192.168.1.6):80/. And my friends can view the things hosted on my server using my external ip (example http://123.123.123.123:80) but when a friend links back to me to show me what they are looking at and share the moment, I can't view the link, it simply redirects to my router login page.
I had an older linksys router and this could work fine. I could click on the links with my external IP and it routes back to my server for viewing.
Remember to note that I am on the machine that has the server, and I'd like to be redirected out and back to it so we can share pictures back and fourth without me having to replace the external IP address with my local one just to view that link in the browser.
I just installed linux fedora 14 on my hp probook 4320s with installation CD with this name: Fedora-14-x86_64-Live-Desktop. Then I installed it on the hard disk. During installation I chose to encrypt hard disk. When I try to access my hard disk it says "unable to mount 250GB LVM2 Physical Volume, Not a mountable file system". What can I do to get access to my hard disk?
