I recently updated my debian 9.9 machine which installed the 4.9.0-9
kernel. With this kernel, the kvm_intel modules fail to load due to
the following errors:
kernel: [ 6.234764] kvm_intel: Unknown symbol cpu_tlbstate (err -22)
kernel: [ 6.235463] kvm_intel: Unknown symbol mds_user_clear (err 0)
kernel: [ 6.330732] kvm_intel: disagrees about version of symbol
Naturally none of my VM's will start. I have gone through the kvm
debian wiki and tried reinstalling the kvm packages while running on
this 4.9.0-9 kernel but that does not solve the problem. I have to boot
on the 4.9.0-8 kernel if I want to use my VM's. This sure looks like an
upgrade issue and that these modules aren't built for this version of
the kernel. Anyone else run into this? How do I fix it?
