It's looking very good on my 7900X since applying the fixes:
- Rolled back all the "nopv" boot options on Linux VMs (Ubuntu, Mint, Rocky) and they boot quickly.
- Xen Orchestra has its IP address within a minute instead of around 10 minutes
- Xen tools status on the Linux VMs are now showing "installed" (vs "not installed" before fixes)
- No "stuck CPU" messages observed anywhere
What a difference! Thanks!!
