The two latest kernels for CentOS7 are complete fails for running KVM and QEMU guest machines.
Version 3.10.0-1160.76.1 works correctly. Both 3.10.0-1160.80.1 and 3.10.0-1160.81.1 will hang within seconds of launching any virtual machine. It is a HARD hang. I have to pull the power cord from the computer in order to regain control.
Since 81.1 came out within the last few days, I assumed it would contain a fix for this problem. It does not.
Does anyone know when a kernel will be released that fixed this problem?
This is not true for all KVM guests. This kernel is actually installed and test booted before release on a cold iron, KVM VM, Virtual Box VM, and ESXi VM.
It also passes our t_functional test suite:
All C7 updates run through all these tests for all new rpms.
So this problem has some other specific cause. Is this on a E5507 processor?
What OS is the KVM host running. I assume this is x86_64 arch?
