[Fedora-xen] Error creating domain in RHEL5 dom0_min_mem

Hello,
I am trying to install RHEL5 beta2 as a virtual machine in RHEL5 beta2. But
all the time I get this error:
Starting install...
libvir: Xen Daemon error : GET operation failed: No such domain rhel5b2-pv1
libvir: Xen Daemon error : POST operation failed: (xend.err ''Error
creating
domain: I need 262144 KiB, but dom0_min_mem is 262144 and shrinking to
262144 KiB would leave only 235124 KiB free.'')
Failed to create domain rhel5b2-pv1
Traceback (most recent call last):

    main()

  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

createLinux
    if ret is None:raise libvirtError(''virDomainCreateLinux()
failed'')
libvirt.libvirtError: virDomainCreateLinux() failed

Note that I have tried both GUI and command line but all the time the same
error.
Here is my grub.conf file:
title Red Hat Enterprise Linux Client (2.6.18-1.2747.el5xen)
        root (hd0,5)
        kernel /boot/xen.gz-2.6.18-1.2747.el5 dom0_mem=256M
        module /boot/vmlinuz-2.6.18-1.2747.el5xen ro root=LABEL=/ rhgb quiet
        module /boot/initrd-2.6.18-1.2747.el5xen.img

Note that I have only 512 MB RAM available.
Please help.

Re: [Fedora-xen] Error creating domain in RHEL5 dom0_min_mem

So your dom0 is set to keep 256M (262144) of memory.
For a RHEL/FC6 guest 256MB is really the base for the install to run in
anaconda - you''ll get mixed results with less, although after install
you can safely drop it down.
Are you saying that you have 512MB total available or 512 free after
dom0 takes it''s share?
It looks like you''re asking for 262144 kb (256MB) of memory for your
guest is that right ?

What does xm list show for dom0''s memory - have you tried running xm
mem-set in dom0 to reduce it''s memory?

Re: [Fedora-xen] Error creating domain in RHEL5 dom0_min_mem

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.
