We running cloud on XCP, I can say, that cpu performance is negligible
factor for current hypervisors state. The main problem starts around
network and disk performance, and balance of features/speed of them.
Our virtual machines boots within this time (10s and less) and I can't
say this is somehow critical question. More important is, f.e. footprint
on dom0 for network performance. I somehow unhappy of XCP performance -
I getting only 5-7GiB/s with about 100% load of one dom0 vCPUs. I've
prefer to see something around 8-9GiB/s with much lower load, but not
sure if any other system with bridge level aggregation and live
migration could perform better.
Same for disk IO - XCP do have relatively slow ISCSI, performing only
around 300-500MB/s (instead expected over 1GB/s), but, again, I saw
nothing better right now.
One problem with 'slow XCP' may be within HVM - which is lame mode for
lame windows-based appliances.

I originally used the XCP ISO but had to ditch it because XCP wasn't
easily compatible with the software raid scenario that we used and
since have jumped over to KVM.
Personally I have never seen any hypervisor even come close to the
performance I have gotten from the Paravirtualization KVM solution on
Debian. It blows everything else I have used to date (all freeware,
ESXi and XCP 1.1) for small business. But I would like to know what
am I missing by going with para virtualizatoin like KVM over a
hardware thingy mbob (cant remember the actually name sorry, its the
one where the VM gets direct access to the hardware). I have windows
server 2008 w/ 2 VCPU's and 1024mb of VRAM booting up in 10 seconds
and shutting completely down in 10 seconds. This is light years
better than even with dedicated software. The hyperthreading seems to
be exactly as it should, so for a small business (or even a larger
business such as UBISOFT) what benefits does one have using XCP over
something like KVM.
I am simply asking because I don't understand why everyone on the
planet hasn't jumped onto KVM's.
Thank you and no fanboyism junk here, simply want to know for the sake
of having knowledge.

Hi,
I am working in the Ubisoft Cloud team and we are waiting for XCP
1.5 to be released. Looking at the roadmap, RC1 should have been
released in November and Final release in December. Is there any
news on XCP 1.5 release date or RC1 download? If found the dates
