Implement memory failure event for virsh command and test.
Notice:
The full patch set includes 4 patches:
virsh: implement memory failure event (current patch)
qemu: monitor: handle memory failure event
qemu: process: implement domainMemoryFailure
API: introduce memory failure
To avoid build/test errors, the 4 patches should be merged/removed
together. Test all the patches with a little complex environment
(nested KVM):
1, install newly built libvirt in L1, and start a L2 vm. run command
in L1:
~# virsh event l2 --event memory-failure
2, run command in L0 to inject MCE to L1:
~# virsh qemu-monitor-command l1 --hmp mce 0 9 0xbd000000000000c0 0xd 0x62000000 0x8c
Test result in l1(recipient hypervisor case):
event 'memory-failure' for domain l2:
recipient: hypervisor
action: ignore
flags:
action required: 0
recursive: 0
Test result in l1(recipient guest case):
event 'memory-failure' for domain l2:
recipient: guest
action: inject
flags:
action required: 0
recursive: 0
