[libvirt] Unmarshalling error with migrate command
Hey guys, I'm using a server running libvirt 0.8.2 and my desktop running libvirt 0.8.2. My desktop has virt-manager 0.8.4 and I've got a Linux VM running on the server. I'm looking to use the new migration support to migrate the VM to my desktop from the server. Everytime I attempt the migration I get an error dialog containing the following (I've actually snagged this out of ~/.virt-manager/virt-manager.log [Wed, 07 Jul 2010 18:13:23 virt-manager 18880] DEBUG (migrate:456) Migrating vm=CentOS-5.4-i686-PAE from qemu+ssh://root@codeine/system to qemu:///system [Wed, 07 Jul 2010 18:13:23 virt-manager 18880] DEBUG (domain:1351) Migrating: conn=<libvirt.virConnect instance at 0x2a305f0> flags=7 dname=None uri=qemu://doug-pc/system rate=0[Wed, 07 Jul 2010 18:13:23 virt-manager 18880] DEBUG (error:86) Uncaught Error: unmarshalling remote_error : Unable to migrate guest: Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/migrate.py", line 457, in _async_migrate vm.migrate(dstconn, migrate_uri, rate, live, secure) File "/usr/share/virt-manager/virtManager/domain.py", line 1352, in migrate self._backend.migrate(destconn.vmm, flags, newname, interface, rate) File "/usr/lib64/python2.6/site-packages/libvirt.py", line 479, in migrate prefer to invoke virDomainMigrateToURI, avoiding the need to libvirtError: unmarshalling remote_error If anyone has any ideas, please let me know. -- Doug Goldstein

We did have a bug with this, but I'm pretty confident it was fixed in libvirt 0.8.1, which makes the above odd. Are you absolutely sure it's 0.8.2, and you aren't using some older version somewhere on the server or on your desktop? -- Chris Lalancette

I unfortunately have to reply to myself since Google Apps or whatever the heck its called now ate the response. remote: virsh # version Compiled against library: libvir 0.8.2 Using library: libvir 0.8.2 Using API: QEMU 0.8.2 Running hypervisor: QEMU 0.12.4 local: virsh # version Compiled against library: libvir 0.8.2 Using library: libvir 0.8.2 Using API: QEMU 0.8.2 Running hypervisor: QEMU 0.12.4 They're both Gentoo boxes. I maintain the packages for Gentoo. After an upgrade of the package we stop the daemon and start it back up without touching any of the VMs (since libvirt supports this gracefully now). -- Doug Goldstein
