[Fedora-xen] guest install with loop backed FC5 dvd iso image
I am trying to do a guest install of FC5 on a FC5 machine. Xen is running. I
am having problems
with setting up a proper guest location for the install.
I did a loop back mount of a DVD iso image for FC5, then shared it with NFS
in theory I want to use this to load my guest in xen.
mount -o loop -t iso9660 FC-5-i386-DVD.iso /mnt
then share /mnt on nfs.
xenguest-install.py
What is the name of your virtual machine? guest1
How much RAM should be allocated (in megabytes)? 256
What would you like to use as the disk (path)? /home/myhome/guest1
What is the install location? nfs:192.168.1.100:/mnt
is the path here correct or do I need a sub directory of the ISO image for
location ?
here is the debug:
Starting install...
libvir: Xen Daemon error : POST operation failed: No such domain guest1a
Failed to get devices for domain guest1
Traceback (most recent call last):
File "/usr/sbin/xenguest-install.py", line 460, in ?
main()
File "/usr/sbin/xenguest-install.py", line 451, in main
start_paravirt_install(name, ram, disk, mac, uuid, src, options.extra)
File "/usr/sbin/xenguest-install.py", line 331, in
start_paravirt_install
dom = conn.createLinux(cfgxml, 0)
File "/usr/lib/python2.4/site-packages/libvirt.py", line 207, in
createLinux
if ret is None:raise libvirtError(''virDomainCreateLinux()
failed'')
libvirt.libvirtError: virDomainCreateLinux() failed
Has anyone seen this problem and know how to work around it.
thanks,

Ok, solved this problem by reducing the memory in dom0 to 128 meg. xm mem-set 0 128 and using 256 meg in the guest. not a very graceful error but the blue install FC5 screen is up. Ron.

this install if fighting me on every step. So now I am progressing on the FC5 guest install and it can not access my nfs /mnt drive with the FC5 dvd iso, it is shared R/W from my dom0, any ideas to try ? I get to the screen that asks for the nfs server and directory to mount. thanks, Ron.

The only issue there ever was was a performance issue, with the glibc variant that uses negative segment offsets. Current Fedora has a glibc variant that does address calculations to avoid the negative segment offsets. This removes the performance penalty FC4 had. -- All Rights Reversed
