does virsh managedsave/restore work?

[mailinglists35]

I removed cpu flag invtsc to allow virsh saving (opencore allows booting without +invtsc), however on restoring it doesn't work. anyone managed to get save and restore? the other more recent project seem to not have allowed discussions nor issues

ah it is simple, managedsave-edit and remove the offending flags. seems they are not supported by host cpu
