[Xen-users] Re: Xen-users Digest, Vol 68, Issue 41

[Jonathan Lettvin <jlettvin@xxxxxxxxx>]

Thank you, all.
I will try these.
If I succeed in mounting a xen
I will write start-to-finish instructions
and make them available.

I don't have personal experience with Lenny, perhaps the xen-users list does.

I see Debian does have kernels:
http://wiki.xensource.com/xenwiki/XenDom0Kernels

Anybody running Xen + Dom0 kernel successfully on Lenny?

See Jonathan's question below.

Thanks,
Todd

Hi George,

That's a slightly odd part of the build. What's going on here is that the 'loader' file comes from the anaconda RPM, and has to be there because we've fixed an issue with recognising xen block devices. Now, I don't believe we provide a patched SRPM for anaconda. But it turns out that's just because we've been lazy rather than we're hiding any code. 'loader' is part of anaconda, but the change is in a staticly linked library provided by kudzu. Probably what we should have done is explicitly produce a new anaconda SRPM with a buildrequires line that mentions the required version of kudzu. But we haven't - yet.

So, to build this file, you'll need to install the patched kudzu rpm, then get the standard anaconda SRPM from the RHEL repositories, and rebuild that.

I haven't actually tried this myself, but I'm assured this is how it works :-)

Cheers,

Jon

Todd,

Just run
# apt-get install linux-image-2.6.26-2-xen-686

It will resolve the dependency problem and install the linux-image with
Xen support for you.

I'm running Xen with Debian with (almost) no problems for a while, the
only critical problem that I had is a machine that just rebooted after
492 days running with no reason at all... but if it happens every 492
days, I can leave with that.

Regards,

Fábio Catunda.

Hi Guys,

I have up2date XEN- and Kernel-Packages for most Common Distris like
Fedora 11-13, Centos 5, RHEL6, Debian and Ubuntu 10.XX, so you can use
Distris-Package-Manager to get a running XEN-System in about 15 minutes.

Let me know if anybody is interested.

cu,

thomas
