Hi, I have a server with Supermicro X7DVL-3 (P9) motherboard, 16G ECC RAM and LSI SAS 1068e RAID controller. I installed CentOS 6.5 64bit on the machine without any problems, but after following the Xen setup steps at [1]http://wiki.centos.org/HowTos/Xen/Xen4QuickStart which installed me the kernel 3.10.32-11.el6.centos.alt.x86_64, I encountered a problem: After "Starting certmonger [OK]" the screen went black and the system became unresponsive: keyboard was not working (NumLock did not respond) and SSH was not responding either. After first lockup I increased dom0 max mem to 2G, but rebooting after that produced the same result. The strange thing is, that after a third reboot everything worked ok: screen went black for a moment after "Staring certmonger [OK]" but after that the graphical login screen appeared and I could use the system normally. The fourth reboot went ok as well. Any ideas what could cause this kind of behaviour?
No idea really.. but what you should do is to enable/configure a serial console, probably by using the IPMI SOL, so you can capture and log all the Xen and dom0 kernel boot messages..
So we can hopefully *see* what the issue is, and not have to guess :)
