not sure what two instances of the same hdd you mean, but that would certainly make a big mess
this time with the proper config. I also removed the hardcoded cpu placement and let libvirt decide.
well, that'll be up to the kernel. You can keep it in and it will provide some boost if it's correct.
thanks for all the help
I'm glad you figured something out, I was a bit unsure about what is happening on you end, so it's good to know there's progress.
