[libvirt] LIBVIRT migration
Hello I'm having problem using migration. I'm working on ubuntu 10.4 and this versions of libvirt and virsh: virsh # version Compiled against library: libvir 0.7.5 Using library: libvir 0.7.5 Using API: QEMU 0.7.5 Running hypervisor: QEMU 0.12.3 This is the error. *virsh # migrate scompi1 qemu+ssh://rionegro/system error: Unknown failure * This is the log on the destination, that show that there is no communication problem, but it has a problem starting the guest on destination. radic@rionegro:~$ sudo cat /var/log/libvirt/qemu/scompi1.log [sudo] password for radic: LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin QEMU_AUDIO_DRV=none /usr/bin/qemu-system-x86_64 -S -M pc-0.12 -enable-kvm -m 4096 -smp 4 -name scompi1 -uuid 355123af-b683-9fa6-ca31-10506c9ab9da -chardev socket,id=monitor,path=/var/lib/libvirt/qemu/scompi1.monitor,server,nowait -monitor chardev:monitor -boot c -drive file=/home/radic/mvdata/imagenes/scompi1.img,if=ide,index=0,boot=on,format=raw -drive if=ide,media=cdrom,index=2,format=raw -net nic,macaddr=52:54:00:05:d1:2a,vlan=0,model=virtio,name=virtio.0 -net tap,fd=33,vlan=0,name=tap.0 -chardev pty,id=serial0 -serial chardev:serial0 -parallel none -usb -vnc 127.0.0.1:0 -vga cirrus -incoming tcp:0.0.0.0:49153 char device redirected to /dev/pts/1 LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin QEMU_AUDIO_DRV=none /usr/bin/qemu-system-x86_64 -S -M pc-0.12 -enable-kvm -m 4096 -smp 4 -name scompi1 -uuid 355123af-b683-9fa6-ca31-10506c9ab9da -chardev socket,id=monitor,path=/var/lib/libvirt/qemu/scompi1.monitor,server,nowait -monitor chardev:monitor -boot c -drive file=/home/radic/mvdata/imagenes/scompi1.img,if=ide,index=0,boot=on,format=raw -drive if=ide,media=cdrom,index=2,format=raw -net nic,macaddr=52:54:00:05:d1:2a,vlan=0,model=virtio,name=virtio.0 -net tap,fd=33,vlan=0,name=tap.0 -chardev pty,id=serial0 -serial chardev:serial0 -parallel none -usb -vnc 127.0.0.1:0 -vga cirrus -incoming tcp:0.0.0.0:49154 char device redirected to /dev/pts/2 LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin QEMU_AUDIO_DRV=none /usr/bin/qemu-system-x86_64 -S -M pc-0.12 -enable-kvm -m 4096 -smp 4 -name scompi1 -uuid 355123af-b683-9fa6-ca31-10506c9ab9da -chardev socket,id=monitor,path=/var/lib/libvirt/qemu/scompi1.monitor,server,nowait -monitor chardev:monitor -boot c -drive file=/home/radic/mvdata/imagenes/scompi1.img,if=ide,index=0,boot=on,format=raw -drive if=ide,media=cdrom,index=2,format=raw -net nic,macaddr=52:54:00:05:d1:2a,vlan=0,model=virtio,name=virtio.0 -net tap,fd=33,vlan=0,name=tap.0 -chardev pty,id=serial0 -serial chardev:serial0 -parallel none -usb -vnc 127.0.0.1:0 -vga cirrus -incoming tcp:0.0.0.0:49155 char device redirected to /dev/pts/2 I'm attaching the xml of the scompi1 that i'm trying to migrate.

Hello: I did more tests, but I don't find the problem. this is a debug I've got setting LIBVIRT_DEBUG=1, I'd appreciate any help. Regards. Marcela. 2011/4/4 Marcela Castro León <mcastrol@gmail.com>

This is the error. *virsh # migrate scompi1 qemu+ssh://rionegro/system error: Unknown failure *
This is the log on the destination, that show that there is no communication problem, but it has a problem starting the guest on destination.

[snip] Are you sure the domain name is OK for the case of this attempt where you got the log files ? error: failed to get domain 'scmpich1' error: Domain not found: no domain with matching name 'scmpich1' This seems like the domain doesn't exist neither on source nor on target system.

Hello: I did the migration test again and this are the result: a) I define the guest scmpich1 on "santacruz" b) scmpich1 started and I connected to it (ssh) OK (the debug is on create_scmpich.log) c) I migrate it to rionegro host. ** virsh # migrate scmpich1 qemu+ssh://rionegro/system It finish with *error: Unknown failure *(the debug of this is on mig_scmpich1.log) d) I send you the log of /var/log/libvirt/qemu/scmpich1 on origin (santacruz) and on target (rionegro). Thank you very much for your help. Marcela. 2011/4/5 Michal Novotny <minovotn@redhat.com>
