The unhelpful error message is coming from qemu. I'm not sure it makes any sense to save/restore a domain with host devices assigned (I'm afraid they the devices will be in different internal state when the domain is resumed) but I will reassign this to qemu-kvm for now to check what's going on... Could you attach /var/log/libvirt/qemu/winsrv.log file, which contains the command line qemu-kvm was started with and hopefully also some more messages from qemu. Created attachment 575400 [details]
As you requested: /var/log/libvirt/qemu/winsrv.log

VM config winsrv.xml
save/restore of domains with assigned devices is not supported. The error message is not friendly, but this is not critical and has been improved on upstream (so RHEL7 will have it right). Closing bug as deferred because the "undefined error" will be fixed in RHEL7 (although the use case will still be invalid). *** This bug has been marked as a duplicate of bug 805172 *** |
The command: virsh save winsrv testsavefile get an error like: QEMU «migrate»: An undefined error has ocurred if the config file to remove the block containing: <hostdev mode='subsystem' type='usb' managed='yes'> <source> <address bus='2' device='3'/> </ source> </ hostdev> and then: virsh save winsrv testsavefile saves the file without errors. libvirt-python-0.9.4-23.el6_2.7.x86_64 libvirt-client-0.9.4-23.el6_2.7.x86_64 libvirt-0.9.4-23.el6_2.7.x86_64 qemu-kvm-0.12.1.2-2.209.el6_2.4.x86_64
