Thanks Andrew. I found a few links on how to install any OS on hvm, so I
think I''m good there. But what about the key question:
Does Linux (either in HVM mode or in paravitualized mode) support the
"cores-per-socket" paramter?
I''m concerned that xcp doesn''t support it, since this website
(
http://support.citrix.com/article/CTX126524) has the sentence:
"Note: This procedure does not apply for Linux virtual machines."
but I don''t know if what they really meant to say is "This does
not applyt
to ***PARAVIRTUALIZED*** linux machines, but it would apply to any HVM
machine".
