[Bug 2158462] Re: Malformed HV_LINUX_VENDOR_ID breaks VM Availability Metric on Azure

This bug is awaiting verification that the linux-nvidia- bos/7.0.0-2018.18 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-resolute-linux-nvidia-bos' to 'verification-done-resolute-linux-nvidia-bos'. If the problem still exists, change the tag 'verification-needed-resolute-linux-nvidia-bos' to 'verification-failed-resolute-linux-nvidia-bos'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

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.
