XCP on intel i9 12th or 13th generation
-
Hello everyone.
I thing buy a new CPU for use with xcp-ng, but I have a doubts about how XCP works with Hybrid CPUs (P-Cores and E-Cores) .
Ej. xcp use all Cores or only P-Cores? How xcp works with the VMs and P-Cores and E-Cores
How xcp works with the VMs and P-Core and E-Core?
someone know about it?
Thanks Every One.

Hi,
After a discussion with a Xen dev, the potential outcome isn't great. Due to their design, it seems impossible to virtualize those CPUs correctly with Xen. At best, you might have something that could barely work.
If you want to test it, go ahead, but there's 0 guarantee you could do anything with it.
edit: if you can disable all E cores, that might work, what's broken is the hybrid mode

Read that if you want to see how bad Intel was a doing their CPU design: https://github.com/intelxed/xed/commit/7561f549d787edc55949b671dee2255a8435741a
