why does my virtual machine freezes when I flush iptable rules. i tried to install virtual machines 3 times and every time I flush iptables on host, virt machine freezes down. What can be the issue? Is it with the host installation or something else?
View 5 RepliesI have 3 boxes running opensuse-11.4 64 bit - Phenom-I 2.6 GHz, Intel Q9400 quad core 2.66 GHz and Intel SU7300 dual core 1.3 GHz (the last one is a laptop). When I run a KVM virtual machine and load it quite a lot all host OS freeze. Interestingly, the laptop works the longest (hours), while the fastest system with Q9400 freezes in max. 10 minutes. After a hard reboot there is nothing in /var/log/messages This bug is 100% reproducible. The guest OS is either RHEL or openSUSE. Is it a 11.4 bug or I am missing something? Have not tried the same hardware with RHEL-6.

View 3 Replies View RelatedI have a server that is on a high port number, and people want it on port 80. For root exploit issues people say the server can not run as root. So to solve things I want to redirect port 80 to a high port number, say 12345 on the machine. This has been discussed all over the web, so I find I need to do this:
/sbin/iptables -t nat -A PREROUTING -p tcp -d 123.45.67.89 --dport 80 -j REDIRECT --to-ports 12345
/sbin/iptables-save > /etc/sysconfig/iptables
And I do this, an voila things work for the whole world. All machines in the world can see the server on port 80 on the machine.Except, on the machine itself. On the machine 123.45.67.89, I try to get to the server on 123.45.67.89:80, I get a can't connect error. On the machine if I try 123.45.67.89:12345 I can connect.What am I doing wrong here? I don't want localhost network really, I want the ip address and port, but I want the forwarding to work on the local machine. But it doesn't...

View 3 Replies View Relatedpolicy is to backup mysql with mysql-zrm.However at a certain stage it hangs forever. This is at the "flush logs". I tried this manually and it gave the same result. Even after restarting mysql and the host. After some googling and trying I found out "flush tables with read lock" gives the same result. The tables seem to be MyIsam. I tried with a mysqldump on one server and restore it on a test vm. I used the same config and flush logs still hangs. ALso I tried to change some configuration directives... but with the same result
Edit: btw, I checked the logfile and didn't found anything (/var/log/mysqld.log)
Edit2: I also did myisamchk -s *.MYI (in all direcoties with db files;actually did it with find command) and it did not return anything so datafiles seem ok.

View 1 Replies View RelatedI'm running Ubuntu Intrepid on a Dell laptop. I turn it off at night.Every morning when I turn it back on and open Firefox, I have to wait while the machine is busy/freezes for maybe a minute. This usually happens twice, but sometimes three times. The processor light is on solid when it does this.I've run TOP from the terminal, and it says it's XORG that's running.
This only happens when Firefox is running, and when I first turn on the laptop after it being turned off for a while. Every morning, when I first run Firefox, XORG takes control of the laptop. Not a big deal, but frustrating and worrisome.
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 have several others VMs with freeBSD, openBSD or Windows on it, but only ubuntu machine hes network problem after coping. I tried some other VM with ubuntu on it - same problem!

In order to get the work done I use a Macintosh Macbook Pro (4,1) with a Boot camp partition running Windows 7.This allows me to use my favorite OS (OSX) with my required work environment (Win7 & .Net) when ever I need them.To allow me smooth usage I use Parallels 5 to virtually boot my Win7 machine from within OSX but whenever I want to do some heavy lifting I reboot into Windows 7 (on boot camp) which allows me to use my laptop's entire resources for my work.
My problem is this: I am now about to begin work for a company in Tel Aviv which uses Linux desktops for development and I need to follow suit. So I've given my self a new Quest: Set up the ultimate web development platform. My goal is this-
1. Install the three operating systems one along side the other - OSX, Ubuntu & Windows 7.
2. Set each one of them up in such a way that allows me to boot into it (meaning I can have any one of these OSs running on its own when I want.
3. Use parallels to virtually boot my Win7 partition - this allows me to keep using Office 2007, which I use often.
4. optional! Use parallels to virtually boot the Ubuntu OS also.
I have managed to complete goal 1 & 2.But I simply can't get 3...In theory it isn't a problem to install windows & OSX along side each other and virtually boot the windows under OSX using parallel's bootcamp virtualizer- BUT - the moment I install Linux along side the other two it break's parallel's virtualizer and it can't boot. I think it is due to parallel's in ability to use GRUB but I'm not actually sure about that.
I am considering compromising and going for a system like this:
1. Install OSX and Ubuntu on the laptop - which means I can boot into each of them.
2. Create a virtual machine for Win7 using parallels.
But that will be a real compromise as far as I'm concerned and I hope to find a way to set up the machine as I described earlier (three OSs which can be booted independently and also loaded in VMs).Just to make sure I'm clear - I HAVE MANAGED to install three independent OSs on the same machine - but that always prevents me from booting them as VMs using parallels...
I have a main Ubuntu system and a virtual Windows system, set up using QEMU/KVM. So, I can start Windows using virt-manager and connect to it using a VNC client.But what I really want to have is a new Xorg display that is connected to this Windows system, so that e.g. CTRL-ALT-F8 shows Ubuntu, CTRL-ALT-F9 shows Windows. That'd be a real alternative to a Linux/Windows dual-boot setup.
I know that GDM had some option to connect to another X server (XDMCP), but I couldn't get this to work with GDM2/Ubuntu 10.4. Would this somehow also work to connect to a VNC server (like the virtual Windows system)? how to make Xorg provide a display for incoming VNC connections, but nothing on how to do the opposite.
What is the a tried and tested free virtual machine solution like VMware for Linux? I would like to run several different types of OS on a server with an Intel processor?

View 3 Replies View RelatedI have installed the guest OS on the redhat 5 with XEN. I found the guest OS can be started on host boot UP, but it cannot be shutdown on host shutdown. so,I need to creat the script to shut down the virtual machine
The script as following:

VMLIST=`xm list`
for VM in $VMLIST
do
xm shutdown $VM
# delay a bit the next sequence
sleep 3
done
run the script,the virtual machine can be shutdown, bu at the same time the error info will appear:
Error: Domain 'Name' does not exist.
[Code]...
So,all the strings in the line of the output regard as the Name of VM The script will run the command like "xm shutdown Time(s)" ,"xm shutdown State",and so on. How Can I get the guest OS name in the output of "xm list" I just nend to get the virtual machine name, the script to run the command "xm shutdown windows2003" and "xm shutdown windowsXP" how to find the strings "windows2003" and "windowsXP" when input the command "xm list"
