Re: [Xen-users] migrate virtual machine to another server
Hi, If the devices are in /dev/mapper you are probably using LVM. You can use these commands to move the disks to server2 substituting in the names of the LVM logical volume names. # copy the LV to an image file dd if=/dev/mapper/<vgname>-<lvname> of=/tmp/<vmname>.img bs=1M #transfer the image file scp <user>@server2:/tmp/<vmname>.img #create a new LV assuming the volume group is already setup lvcreate -n<lvname> -L<sizeofdisk> <vgname> #copy the image onto the newly created lv dd if=/tmp/<vmname>.img of=/dev/mapper/<vgname>-<lvname> You should now be able to start the VM with the same configuration file assuming networking etc is setup the same as server1.

Re: [Xen-users] migrate virtual machine to another server
Hi, Ensure this path is correct: ''phy:/dev/europe_storage/bill-wdisk,hda,w'', Also if you aren''t using the QEMU ioemu driver make sure you have PVonHVM drivers installed or GPLPV if this is a Windows guest. Is there any error output when you try to start the domain? Joseph.

Re: [Xen-users] migrate virtual machine to another server
I felt i should jump in :) Whenever I do a "vm move" I preffer to keep a snapshot of the machine just in case. On Fri, May 13, 2011 at 11:59:03AM -0400, John Madden wrote:> Tsk, tsk. Do it in one step: > > dd if=/dev/mapper/srcdisk bs=1M | ssh root@targetserver "dd > of=/dev/lvm/tgtdisk bs=1M"To save you some space, you can simply "gzip" the disk: dd if=/dev/mapper/srcdisk bs=64k | gzip -c > srcdisk.gz This has saved me a lot of space. I always smile when my 20-50GB lvm volumes suddenly take up just 5GB of disk space. And obviously you can gzip over ssh too, you''ll just need to gunzip -c and dd with the correct bs on the other end. Depending on your upload speed, this might actually save you some time. I use this to pull images down (over ADSL) from my hoster to the xen test server i have at home.

the path is correct on server 2 is already running multiple virtual machines with Xen. vwindows is that Linux Every machine in the server 2 are all working.
