[Fedora-xen] Error creating domain in RHEL5 dom0_min_mem

[Deependra Shekhawat]

Okay. I got rid of that error. I opened /etc/xen/xend-config.sxp and edited
the
dom0-min-men to 220. But now I have some new errors:
Starting install...
libvir: Xen Daemon error : GET operation failed: No such domain rhel5b2-pv1
libvir: Xen Daemon error : POST operation failed: (xend.err 'Device 0 (vif)
could not be connected. Hotplug scripts not working.')
Failed to get devices for domain rhel5b2-pv1
Traceback (most recent call last):
  File "/usr/sbin/virt-install", line 406, in ?
    main()
  File "/usr/sbin/virt-install", line 370, in main
    dom = guest.start_install(conscb)
  File "/usr/lib/python2.4/site-packages/virtinst/ParaVirtGuest.py", line
202, in start_install
    return XenGuest.XenGuest.start_install(self, consolecb)
  File "/usr/lib/python2.4/site-packages/virtinst/XenGuest.py", line 355, in
start_install
    self.domain = self.conn.createLinux(cxml, 0)
  File "/usr/lib/python2.4/site-packages/libvirt.py", line 249, in
createLinux
    if ret is None:raise libvirtError('virDomainCreateLinux() failed')
libvirt.libvirtError: virDomainCreateLinux() failed

And I have total physical RAM of 512M of which I gave 256M to dom0 and rest
of all I want to give to my dom1. Please help with the above error. I found
that it has been under bugzilla at redhat. But maybe now there exists some
solution to this.
