You will need to rebase for the actions change in #7544. |
The MSR enumeration logic in MSHV does not accurately account for the capabilities of the underlying hardware and hypervisor. Previously, integration tests passed because only the default MSRs—universally supported across platforms—were involved. However, recent feature additions in MSHV have introduced MSRs that are not supported on Intel hardware, causing failures. This patch retrieves the MSRs from the VM specific API call that filters out the unsupported MSRs. Signed-off-by: Muminul Islam <muislam@microsoft.com>
These tests are expected to fail. See: cloud-hypervisor#7542 Signed-off-by: Muminul Islam <muislam@microsoft.com>
