I've just installed a XCP 1.5 Beta on the Oracle X4800 M2 80-CPU server
(available for me for one month testing  ;) and I've found some cosmetic bugs
First of all, I'm very impressed with XCP. server Nice job!

XenServer Build Number: 53341c
SenServer Version: 1.4.90

1) Installation creates wrong (?) Xen-kernel commandline with extra empty
"console" parameter in the "extlinux.conf". As a result I have a
totally blank screen
on boot  for a long long time

See line 12

2) (XEN) Scrubbing Free RAM: a TOOOOO long process for the 256Gb of RAM

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)

4) During boot process the virtual BIOS on the HVM machine displays 1 CPU only

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

6) The worst bug: The XenCenter 6.0.2 can't display "Performance" tab
(for 80 CPUs ??) ,
an exception generated:
