Hello when I tried to migrate a VM from on virtuozzo 7 host to an other one I get a CPU capabilities not provided by destination
# prlctl migrate myVM root@olympos -v 16 Logging in ... security_level=2 PrlCleanup::register_hook: 8780700 EVENT type=100030 Migration started. EVENT type=100001 EVENT type=100033 Operation progress ...98%EVENT type=100033 Operation progress 100% EVENT type=100033 Operation progress ... 0%EVENT type=100031 Migration cancelled! EVENT type=100007 EVENT type=100001 Failed to migrate the VM: Operation failed. Failed to execute the operation. (Details: the CPU is incompatible with host CPU: Host CPU does not provide *required features: hle, rtm, rdseed, adx, smap, 3dnowprefetch*) resultCount: 0 PrlCleanup::unregister_hook: 8780700 Logging off indeed those capabilities don't show up in the lshw on the destination host (cf PS below ) alhtough myVM doesn't seem to require those capabilities : # virsh edit myVM ... <os> <type arch='x86_64' machine='pc-i440fx-vz7.7.0'>hvm</type> </os> <features> <acpi/> <apic/> <pae/> <vmcoreinfo state='on'/> </features> <cpu mode='host-model' check='partial'> <model fallback='allow'>Skylake-Client-IBRS</model> <topology sockets='1' cores='2' threads='1'/> * <feature policy='require' name='ss'/>** ** <feature policy='require' name='hypervisor'/>** ** <feature policy='require' name='tsc_adjust'/>** ** <feature policy='require' name='ssbd'/>** ** <feature policy='require' name='stibp'/>** ** <feature policy='require' name='pdpe1gb'/>* <feature policy='disable' name='arat'/> <feature policy='disable' name='xgetbv1'/> <feature policy='disable' name='vmx'/> <feature policy='disable' name='xsavec'/> <feature policy='disable' name='mpx'/> </cpu> 1) Is it libvirt or virtuozzo (prlctl) that complains about that ? 2) how can I tell it to forget about those capabilities ? 3) should I edit myVM properties with virsh edit or prlct or virt-manager ? 4) are they all compatible (on can read change done by the other ) ? Thanks .
