Hi,
I just received a Supermicro server back from factory repair.
Installed CentOS 6.3 x86_64 fresh from DVD (tried with 6.4, same
result). Everything goes fine until i install Virtualization* yum
groups. Virtualization is enabled in BIOS. Server boots, CentOS loads
and i have even a login prompt. If i'm fast enough to enter login name
and password, shell works for about 10 sec. Then, it seems to hang.
Pressing CTRL-C seems to work as i see it on screen (CTRL-C text).
I'm used to Xen in CentOS 5 where we can choose a non-Xen kernel at
boot time. With CentOS 6 and KVM, i'm kinda lost! I Googled a lot and
didn't find anything to disable KVM / select a a non-KVM kernel a boot
up time. The server has been repaired but i'm not sure if there is
still other problems that prevent KVM to work. I know that they
installed the last BIOS version. I have other identical servers that
works well with KVM. I tried to disable all i saw for virtualization
support in BIOS, result is the same. I did memtest86 tests without problem.
Here are the specs:
Supermicro 6026T-3RF (mainboard X8DT3-S)
BIOS 03/17/12 15:50:21 Ver 2.1
Xeon E5520
Kingston 12 Gig RAM (Triple Channel)
LSI 9240-8i
What should i do to debug this? Any pointers, URL, etc would be
greatly appreciated!
Thanks all.

With CentOS 6 and KVM, i'm kinda lost! I Googled a lot andThe "choose a kernel" is the grub menu, and unless you've disabled it, you can still do it. Try hitting any key as soon as you see the "about to boot ... in x sec" I'd boot to single usermode (s at the end of the kernel line), and check the logs. And I really, *REALLY* don't like Supermicro. We've got a large bunch of servers from Penguin, who's all Supermicro, and we've sent a ton back for repair, as well as doing things here, *and* several of those sent back were sent back more than once. Luck. mark

I'm not saying VMWare is not good though, it's just i hate their tools. On top of that, it can cost a lot of money. But they have the features! I moved to KVM and i'd say i like it a lot. I'm planning to test OpenStack. For storage, big names (3Par, Netapp, etc) offer nice things but it is rather expensive. I'm testing iSCSI servers with DRDB, STONITH, etc. Idea is to use commodity hardware and standard software. Nothing new and i'm not against commercial solution with support and all. It's just we try to offer affordable and open solutions.
> With CentOS 6 and KVM, i'm kinda lost!With KVM you do not have a second kernel but modules installed and my check running: lsmod | grep kvm If you get nothing back you do not have KVM installed, otherwise you should have something like: kvm_intel 132873 0 kvm 438094 1 kvm_intel If you have an AMD processor the module will be named differently.
