I am building a home lab and will be glad to test the new XCP with Cloudstack on top. Followed the repo!
alright i managed to put my hands on such host.
out of 128 cores (including hyperthreading) i managed to create a Debian 11 vm with 108 cores. if i go higher i get an error.
I assume the error is due to some threads being exclusive for the hypervisor. Its possible that is the actual limit too though.
Not that important though just got curious how far i can push it.
What is the maximum amount of cores that can be assigned to a VM?
I know the max limit known is 32 but can I make it more?
For example - if we buy 2 x CPUs that have 32 cores like AMD EPYC. Is there a way to override the limit so i can assign all the 64 cores to the VM? or even better all the 128 threads to the VM ?
