[libvirt PATCH v4 0/4] Add support for QEMU's fmode and dmode
by Brian Turek 04 Nov '20

04 Nov '20

This is the latest set of patches to expose QEMU's fmode and dmode functionality. I hopefully split these up correctly per Peter Krempa's guidance. I debated where to implement the fmode/dmode value validation and ultimately decided on domain_conf.c rather than qemu_validate.c. My reasoning being that it is essentially enforcing the schema rather than performing QEMU-specific validation.

[PATCH v2] cpu_ppc64: compare CPU function is ignoring return value
by Julio Faracco 04 Nov '20

04 Nov '20

Function to compare CPU on 64-bits PowerPC is ignoring the flag to avoid failure in case of CPUs (host and guest) are incompatible. Basically, the function is returning -1 even if it is set to continue.

Hyper-V CPU details
by Matt Coleman 04 Nov '20

04 Nov '20

Hello, I'm implementing domainGetVcpus and could use some guidance on what value to use for virVcpuInfo->cpu. Hyper-V does not allow the user to pin vCPUs to host CPUs and doesn't allow the user to see which host CPU a vCPU is currently running on. Since it's a type 1 hypervisor, none of its scheduling data is available to the Windows userspace: there aren't any processes or threads that correspond to vCPUs that I could query the OS scheduler about. My code currently sets it to -1, which produces the following `virsh vcpuinfo` output for a running VM with two cores: VCPU: 0 CPU: -1 State: running CPU time: 1684.5s CPU Affinity: yyyy VCPU: 1 CPU: -1 State: running CPU time: 1346.0s CPU Affinity: yyyy However, this doesn't match the comment in _virVcpuInfo's declaration, which says that -1 signifies an offline CPU: https://gitlab.com/libvirt/libvirt/-/blob/v6.8.0/include/libvirt/libvirt-do… Should I stick with -1? Or, should I introduce -2 as a value that indicates that the hypervisor doesn't provide that information? Or, is there some better way to handle this that I'm not aware of? -- Matt
