Be warned for anyone interested in running 32bit guests on 64bit dom0 instances that it us currently not supported in CentOS 5.1. This will apparently be corrected in the upcoming release of RHEL (5.2) which is scheduled to make it’s appearance in a month or so. (It should have left beta May 7th).

The stability is SO bad that the image won’t even stay up for a single day. You have been warned. Stay away from mixing 32 and 64 bit Guests. Note that this has long been fixed in the Xen repos. One would just have to figure out how to go about building Xen by himself. Not suggested for production environments either..

CentOS 5.2 came out this week. I’ve been looking forward to this release now for some months because it adds support for 32 big images on 64 bit dom0s.

Previous attempts to use 32 bit images on 64 bit dom0s resulted in serious domU crashing goodness. (The image wouldn’t stay up for more then a day or so…) The New RHEL/CentOS release back ports Xen 3.1 which fixes these issues.

I’ve always had problems running SRCDS servers on 64 bit images and therefore wanted this 32 bit support. For some reason I only get half of the server fps that I should with 64 bit images. For example a 500fps server would only run at 250fps. Though I have seen success stories when using 64 bit UNIX distros I never looked into fixing it properly because of my peculiar setup.

With the new update I’ll be shifting back to using 32 bit images for hosting my SRCDSservers. I mean after all, the SRCDS binaries are i686 .
