Please upgrade kernel so we can do nested KVM virtualization #11

Closed shawnl closed 5 years ago

shawnl commented 5 years ago

nested KVM virtualization for PPC KVM-HW is in Linux v4.20. My current problems wouldn't be so bad if I just left my system up in running, because I could run nested virtual machines.

Also, it is possible this is the reason that kernel's later than Debian's 4.19 are crashing. (if so, that bug should reported)

Also, my systems are refusing to reboot.

We use kernel v4.15, and we can't upgrade it to a new version.
