Public bug reported:
SRU Justification
[Impact]
Commit 56f727d2cc7a ("UBUNTU: SAUCE: (no-up) hv: Supply vendor ID and
package ABI") introduced a regression that breaks the VM Availability
Metric functionality on Azure due to a malformed HV_LINUX_VENDOR_ID
being reported to Hyper-V. This impacts customers that rely on that
metric to assess if their VMs are in a healthy state or not.
[Fix]
The HV_LINUX_VENDOR_ID should be 0x8180 rather than 0x80; this issue can
be fixed by adjusting the value of the constant in all generic kernels
affected by this.
[Test Plan]
Compile and boot tested; verified that the metric works on an Azure VM
running a kernel with the fix. Microsoft is to perform validation on
their side as well.
[Regression Potential]
Low regression potential, but could impact the identification of Ubuntu
guests on Azure.
