In short - virt-manager, and virt-install have problems creating and starting
virtual machines. 


Version-Release number of selected component (if applicable):
[root@localhost data]# xm --version
Error: Sub Command --version not found!
[root@localhost data]# virt-manager --version
usage: virt-manager.py [options]

virt-manager.py: error: no such option: --version
[root@localhost data]# virt-install --version
usage: virt-install [options]

virt-install: error: no such option: --version

[root@localhost data]# rpm -qa | grep xen
kernel-xen-2.6.18-1.2849.fc6
xen-3.0.3-0.1.rc3
kmod-nvidia-xen-1.0.9742-1.2.6.18_1.2849.fc6
xen-devel-3.0.3-0.1.rc3
xen-libs-3.0.3-0.1.rc3

(You guys should _really_ make it easier to determine versioning information on
the tools, if you want it in the bug reports.)


How reproducible:
Reasonably.


Additional info:
I tried to create a new VM using both virt-install, and virt-manager and each
time it came up with :
libvir: Xen Daemon error : POST operation failed: (xend.err "Error creating
domain: (12, 'Cannot allocate memory')")
Failed to create domain test

I tried a lot of combinations of disk size, and memory allocated to the VM, from
as low as 50MB (RAM) to 10GB (Disk) without any success.

I was told a reboot might fix this (what is this - Windows?), and for some
reason it did appear to fix it. No VMs existed prior to this testing with Xen.

I was then able to create a test VM (domain?) with 500MB for RAM, and a 10GB
disk with the XP ISO as the installation medium, using virt-manager's "New" button.

It proceeded to show a GUI with the installation process of installing the files
required for XP to the disk. It then asked to reboot (in 15 seconds) and did...
but the window disappeared. The line in virt-manager for the "test" VM
disappeared too. I attempted to re-open the VM by selecting the disk image -
this didn't work. I then re-attempted with the /etc/xen/test file and it
complained that it was already running. If it was running, then shouldn't it be
listed in virt-manager?

As a side note - I received this warning at the top of the man page for xm:
XXX
XXX WARNING: old character encoding and/or character set
XXX

Running "xm create test" It appeared to start the VM, but no GUI appeared.
running virt-manager and selecting the test VM and selecting "Open" results in a
black screen.
