Unavoidable to have stable system.

3) dom0 boots with 32 CPUs . Seems, CPU for dom0 should be limited to
15..20% of the total CPUs (for very intensive I/O)
You can change this parameter as property of dom0 virtual machine (via xe vm-param-set)

4) During boot process the virtual BIOS on the HVM machine displays 1 CPU only
AFAIK this is feature.

5) YUM update does not work:

# yum check-update
Loaded plugins: fastestmirror
Determining fastest mirrors
Could not retrieve mirrorlist
http://updates.vmd.citrix.com/XCP/1.4.90/domain0/mirrorlist error was
[Errno 14] HTTP Error 404: Not Found
Error: Cannot find a valid baseurl for repo: citrix
This is ...em... the way Cirtix separate XenServer from XCP: no updates for XCP at all. And note that yum update with CentOS repos enabled can make your XCP broken (especially lvm2 package you shall never update from upstream).
