Allow saving and restoring state for a running Windows VM #1269

Closed mbg-unsw closed 4 weeks ago

mbg-unsw commented 1 month ago

Expected behavior

I'd like to be able to use 'savevm' to save the state of my running Windows 11 VM.

Actual behavior

malcolm@tilidine:~/src/quickget$ nc -U "windows-11/windows-11-monitor.socket"
QEMU 8.2.1 monitor - type 'help' for more information
(qemu) savevm 20240604
savevm 20240604
Error: State blocked by non-migratable CPU device (invtsc flag)

Additional context

Looking at the quickemu code, migratable=no is always set for Windows guests. But it seems that setting tsc-frequency to a fixed value should allow migration.

This isn't exactly the same issue as #1261, which has to do with EFI firmware instead, but it should be tracked alongside it.
