Re: Problem installing FC5 guest in Xen on FC5 using xenguest-install.py



OK, I finally got it installed.  Perhaps I was trying something you're not supposed to do.

First of all, the xen0 machine is a VMware image.  This caused a problem I hadn't forseen - apparently VMware's NAT server is fussy about any machine other than the one launched asking for an IP address.  There is a NAT setting ("Allow any OUI") which is off by default that needs to be on before it will give an address to any of the xenU domains.

Before discovering that, I attempted to set up a DHCP server on xen0.  This appeared to work, but when I attempted to get an address during installation, I would get "bad checksum" messages on the packets.  I don't know why, but I had to abandon that approach.  I'll have to revisit that, as I'd like to set up xenU domains that can know see and reach each other.

I was trying to install Fedora from the DVD image, which was mounted on the virtual CD/DVD drive.  Since xenguest/anaconda can only accept NFS/FTP/HTTP locations, I had to jump through some hoops to get that done.

I first tried setting up vsftpd and using FTP.  That didn't work well - anaconda crashed badly when it went to get stuff.  So I tried setting up NFS and explicitly exporting the mount point.  That failed with permission errors.  Finally I set up httpd to contain a link to the mounted image in the default http directory.  That worked, after I reset the vif settings to use bridged networking, and turned on the VMware OUI setting.

Now I'm trying to get VNC working.  This has proved problematic, as the xen0 machine doesn't seem to be able to reach the xenU machine, even using the IP address.  So work continues.

Thanks for the suggestions.

I've been running with kernel-xen0-2.6.15-1.2041_FC5 with no problems so
far.  However, I did have problems (thought not with IP address
assignment) with earlier Xen builds.

You might check if you have the kernel-xen-hypervisor package installed.
  I was having problems before when running IIRC .2032; when I upgraded
to .2041, I removed the hypervisor package, and I've been running Xen
fine since then.

Maybe you could post your /var/log/xend.log and /var/log/xend- debug.log;
hopefully others might be able to help given this information.
