  • Not verified: The feature has not been verified yet.
ExpandDisksGate Not supported yet CDI is needed
CPUManager Supported use taskset to do CPU pinning, do not support kvm-hint-dedicated (this is only works on x86 platform)

DownwardMetricsFeatureGate need more information It used to let guest get host information, failed on both Arm64 and x86_64.

The block is successfully attached and can see the following information:
