I am trying to figure out how to get an almost bare metal virtualization running, and having a hard time getting it going I tryied the Virtual Machine manager, but it wont let me do full virtualization.
View 3 RepliesI would like to try putting some kind of free "bare metal" visualization for desktop useage on my laptop. I've been googling about the possibilities, but still I'm not sure which would actually work in my case. I've seen VMWare ESXi which looks ok, but unfortunatelly it is meant for servers and I can't have ESXI and Sphere client on same laptop. Another candidate I found is KVM, but as much I've seen it requires VTx VTd support from hardware, which my laptop can't provide. The same requirements must be met for Citrix Xen Client, which is meant for desktop virtualizations, but because of lack of VTx and VTd, can't be used in my case. Is there any other possibility? Currently I'm using VirtualBox and VMWare player for virtualization purposes, but I would like to pull out more performance out of it, and a heavy OS on top of another heavy OS just isn't the best way.
View 2 Replies View RelatedOne of my desires is to set up my main workstation as a bare metal hypervisor because:
- Legacy issues mean I can't migrate to Linux in one step.
- The flexibility offered by virtualization is appealing.
Are there any resources out there that explain how to set up and manage fedora as a hypervisor and guests within that environment? I expect that I'll need to install a number of packages and to rebuild the kernel but I'm not aware of enough details to get started.
Can I install VMware ESXi on my Dell Inspiron laptop having core i3 processor which has got 4GB of RAM? I can allocate 100GB of hard disk space for that. This is just to practice and explore the features available. Can I install Vmware ESXi iso on KVM hypervisor like installing guest OS?
View 4 Replies View RelatedSo far I have tried PING, rsync, Clonezilla and tar. All have one or another problem. I'm sure that this is in part to my own ignorance and partly due to running the 64 bit version of Karmic, but I cannot seem to find anyone who has real answers.
View 9 Replies View RelatedI'm looking for a way to do a bare metal backup of our server using a tool such as ghost or clonezilla. The limitation is that / is on an mdadm raid 5. The only relevant info I could find on clonezilla's site was:
# Software RAID/fake RAID is not supported by default. It's can be done manually only.
I have two identical servers, one has RHEL 5 and Zimbra installed and the other is currently not really doing anything. Both have hardware RAID (Adaptec) set to RAID10, identical hard drives, etc. The RHEL/Zimbra machine is set up with LVM2. Is it possible for me to hook them up on the secondary NICs and boot the second machine with Knoppix or something else, and easily tell it to duplicate the first machine onto the second, down to the last bit, or do I need to make all the partitions beforehand and dd each one separately?
View 5 Replies View RelatedI have worked on Xen which is being shipped with RHEL 5.4, Is it possible to install Xen hypervisor directly on bare metal, so that we can save resources. I searched in Xen Official site, but could not recognize the product that can be directly installed on bare metal like VMware ESX.

But I haven't I plan on doing it now but I ran into a hardware failure and had to switch to a different set of hardware. I tried going into rescue mode using the fedora 7 install disc, but st0 for tape drives was not available. So I tried using the newest fedora distro, Fedora 13, installation disc and st0 is still not available on there. How to do a restore from tape?
View 2 Replies View RelatedI'm running a x86-based Debian Squeeze LAMP server which is also my gateway between my home network and the big wide world (Shorewall/Shorewall6) As you can guess, when (as it did just recently) the hardware dies and needs to be replaced, the rebuild of a machine which has been tuned and tweaked over years is "interesting", to say the least. I am looking for some software which will allow me to do a bare-metal restore of the software and setups (data is accommodated already, so that part can be ignored) I'd like to use something to create a boot disc (CD/DVD) that I can put in a new machine and get my original setup installed on the new tin automatically.
I looked at Mondo, it looks ideal, but Google hints at problems with GRUB, and incompatibilities with Debian Squeeze....so the questions are:
1) Has anyone run Mondo on Debian Squeeze successfully?
2) Is there a good howto for Mondo on Debian?
3) Is there an alternative that runs on Debian and that fits my requirements?
Are there any open source or third party applictions can could do a bare metal recovery on Debian or any linux machines? We are looking for a solution that won't need a shutdown or reboot.
View 2 Replies View RelatedI had just put the last touch on a snort, mysql, apache, barnyard, base isntall to CentOs 5.3. I noticed that ifconfig displayed an odd virtual nic, and I wanted as little running on this machine as possible. I don't remember specifying that I wanted XEN installed. And on the old lowend machine that is powering this server, Virtualization was the last thing I wanted running on it. I did a google, discovered that the way to remove XEN completely (yum uninstall xen' only removed 'xen' but still, oddly, xen was running after a reboot. Talk about perplexing.

Windows will be used mostly for rdp and for serving asp.net webpages, linux will host some django-applications and a postgreSQL server etc.
View 3 Replies View RelatedI'd like to run a Tor relay, but am trying to understand the security implications. For some time I've run my torrent client in a VirtualBox virtual machine, which is run as a very non-prived user, bridges directly to The Internets, and writes to one directory on the host. My belief is this is about as secure as it can be, but am open to suggestion.If I run a relay in the VM it wouldn't be associated with my use of Tor as a client, which is fine since there is no technical need for them to be connected and it's desirable for security.I read that chroot jails can be broken, particularly when run as root, so I don't really trust that. Also studied a vserver, but it must share the network setup which doesn't strike me as isolated enough.
View 14 Replies View RelatedI installed the latest version of Centos 5.4.It came with Xen version 3.0.2 I think.I am running it on a Dell R510. It supports hardware virtualization.I was able to virtualize Windows XP and Windows 2003 server on it by selecting the install from DVD option.I was having problems trying to get a PCI DekTek card seen by the virtualized Windows domains so I tried to upgrade XEN to 3.4.2.I used the repos available from Gitmo and it went easy.
The only problem is now that when I try to create a "New virtual host" it only allows me to use HTTP, FTP option and not the iso or DVD option. They are greyed out. I was wondering if anyone has had this problem and might know a work around for the Xen 3.4.2 problem. Perhaps a better location for the kernel or something.
i'm a familiar with Linux environement ( fedora 10 user ) and i got a project in a training where i have to create a cluster with two nodes where i have to set up a number of VMs that will run applications such as ( Samba, Ldap, Zimbra, ...) but i don't know how to virtualize on top of a cluster ! i would like to know how that can be done, and how is it possible to let the VMs get ressources ( RAM & CPU ) from the two nodes ??

View 1 Replies View RelatedI have a customer who has (currently) three servers running Centos 5.5, one running Windoze 2003 and around thirty or so workstations running XP Pro.
I've just been reading about RedHat's product - RHEVD and was wondering of anyone knows if this product (or anything similar) is aavailable under CentOS.
Basically what we need to be able to do is to virtualize the XP workstations so that the staff can connect via a browser (inside the office or off-site - or for that matter anywhere) and be presented with a standard desktop.
I know I can achieve this using Citrix XenDesktop or VMWare View but I would prefer to use a FOSS solution if one exists. Having said that it has to be robust and well past Beta
I am in the process of creating a kickstart configuration file for some RedHat 5.5 and Centos 5.5 servers (Production and test respectively).I have googled about a bit but I cannot find a good list of the bare minimum packages required for a command-line system.If anyone knows how I can trim this list down anymore it would be much appreciated. The aim of this kickstart.cfg is to get the system booted to a bare minimum required to install Chef (Server management software). Chef will then setup Apache, Ruby on rails environment etc.
All this server will need to do is, from a static IP, Host a Ruby on rails app, send emails, send data to a server on the web, accept ssh and occasionally and connect to a SMB/CIFS share This list was taken from the anaconda-ks.cfg file after a RedHat install of what I thought was a pretty minimal system onto a VM but I noticed that cups, the avahi daemonsand gam_server are installed and running which I do not believe are needed for a pure web server.I know that these types of questions are hard to answer without a complete knowledge of the operating environment and what "minimum" is in this case ("@core only? but I wanted yum damnit!")

I have centos 5.3 with text console onl, not X server, now I try install solaris 10 at xen with full virtualization (hvm)
Now I have some like "zombie domain"
How I can to kill this? If I reboot the server it doesn't help.
No fonts found; this probably means that the fontconfig library is not correctly configured. You may need to
edit the fonts.conf configuration file. More information about fontconfig can be found in the fontconfig(3) manual page and on [url] Domain installation does not appear to have been successful. If it was, you can restart your domain by running 'virsh start solhvm123'; otherwise, please restart your installation.
Do you know what this a problem?
If I chagne --vnc to --sdl and run below command on my desktop to appear windows and disappear for 1-3 seconds, virt-install -n solekhvm3 --ram 1024 --hvm --disk path=/dev/vol1/solek --sdl --cdrom /dev/cdrom --os-variant solaris10 --force
In log I have:
The word on all lips are "virtualization" so I decided to smell this flavor.
I have a machine running CentOS 5.3 64bit and I have unlimited access to this machine, but I don't want to reach it physically.
Is it possible to install and maintain a virtual medium using ssh or other remote connection?
When I installed the OS I have selected the packets regarding the virtualization, but now from where can I start?
Is somewhere a guide for doing this?
If you select "support virtualization" during install, you get the xen kernel installed.
Some things do not work with this kernel (e.g. nVidia drivers). So my question is whether it is possible to install both kernels (xen and ordinary) and select between them with grub at boot time?
I did try this a while ago, by first installing with xen and then manualy adding the ordinary kernel, but the ordinary kernel failed to boot (for reasons I don't now recall - sorry). Clearly, there must be differences in the "virtualization" build other than the kernel.
The alternative, if I want to play with virtualization, would be to have two entirely separate installations, but this seems like a waste of space when surely almost everything must be identical?
I can't find anything in the Centos Xen documentation about this.
Before I try again I would just like to check if anyone actually knows if this is possible, or if not why not?
Or can it be done with KVM?
I have CentOS 5.5 and try to create KVM virtual machine with CentOS 5.5 as a guest. But when I exec command:
virt-install --connect qemu:///system --name test --ram 1024 --file=/var/lib/libvirt/images/test.img --file-size=10 --vnc --cdrom=/var/lib/libvirt/images/CentOS-5.5-x86_64-bin-DVD-1of2.iso --vncport=10000 --accelerate --os-type=linux --nonsparse --livecd --hvm
such as a roll of aluminum window screen that you might get at Home Depot, and provided that there are no gaps and that it's grounded?

I am trying to install CentOS 5.2, and the installation ran out of disk space after running for about 2 hours.I checked the FAQ, and it said 1.2 GB. The disk is 3 GB. The default install was selected, and I think that it checks for sufficient available disk space before installing. Still, it ran for quite a while before announcing that it was out of disk space.The Installation Guide is not very helpful, since there is a blank page where the disk space requirement is supposed to be. I just picked the default installation. A search of the forums on "not enough disk space" did not return much.
