OK, yes this is the section footer stuff that needs turning off in the older rhel machine types. OK, so fixing section footers and the like get me a bit further, but then I hit: (qemu) qemu-kvm: get_pci_config_device: Bad config data: i=0x8 read: 2 device: 0 cmask: ff wmask: 0 w1cmask:0 qemu-kvm: error while loading state for instance 0x0 of device '0000:00:02.0/vga' qemu-kvm: load of migration failed: Invalid argument But also we have no 7.3 machine type yet so it's a bit early to be testing. I think this bug is fixed with the combinations of bz 1344269, 1344320, 1342015 Do migration compatibility test for rhel7.3: kernel-3.10.0-505.el7.x86_64 qemu-kvm-rhev-2.6.0-24.el7.x86_64 1. rhel7.2.z <-> rhel7.3 (amd host) 1-1 machine type: rhel7.2/rhel7.1/rhel7.0/rhel6.6/rhel6.5 1-2 guest: rhel7.3 1-3 result: pass 2. rhel7.1.z <-> rhel7.3 (intel host) 2-1 machine type: rhel7.1/rhel7.0/rhel6.6/rhel6.5 2-2 guest: rhel7.3 2-3 result: pass 3. rhel6.9-> rhel7.3 (amd host) 3-1 machine type: rhel6.6/rhel6.5 3-2 guest: win2008r2 3-2 result: pass 4. rhel7.3 <-> rhel7.3 (amd host) 4-1 machine type: rhel6.6/rhel6.5/rhel7.2/rhel7.1 4-2 guest: rhel7.3 4-2 result: pass Based on comment #9, set this bug to be verified. |
