Incomplete 3.2 binary packages

Incomplete 3.2 binary packages

[Chris Lalancette]

Hello,
     I went to: http://xen.org/download/dl_32rhel5.html and downloaded the
binary RPMS for 3.2 to do a quick test.  However, it seems that the binary RPMS
don't include the qemu device model, so fully virt guests have no chance of
starting.  It's not a huge deal for me, since I can recompile from source;
however, for those who don't want to do that, or who want to save a little time
(my original goal), it might be nice to include everything needed in those
binary RPMS.  Just FYI.

xen-3.2.0-0xs.centos5.i386.rpm contains /usr/lib/xen/bin/qemu-dm.

When I built the Xen 3.2 binary packages I did check that they
contained roughly the same things in the same places as the upstream
packages, but in general my (very light) testing did not include
starting an HVM guest.  So there may well be a bug here.

Can you confirm that qemu-dm is on your system ?  If not do you know
why not ?  If you have some more information (for example, actual
error messages which show where it is looking for which file) I might
be able to fix it up if indeed it's a bug in the package.

Ian.

WRT to libvirt starting guests, there was a bug in 3.2.0 which prevented
any HVM guest starting - the timer_mode bug - you need this fix otherwise
it simply won't work

Ian, you are completely right, I do have a qemu-dm on my system.  I don't know
how I missed it.  I still am not able to create guests, though; I'll get some
additional debugging data to you.

And this might be it; I'll try with this patch applied.

Oh, crap, never mind.  For some reason I thought these packages had a 64-bit HV,
when they are clearly marked i386, so starting an x86_64 guest isn't going to
work there.  Sorry for the noise.
