Hi, folks. We're finally getting around to trying out the Xen
hypervisor on an SL 5 (x86_64) system here.
I thought it would make sense to start with the simplest configuration
-- just put the whole virtual machine into a single file.
We ran virt-manager and added a virtual machine, evidently successfully.
Here are the details of the file:
# pwd
/virt
# ls -lh
total 4.0G
-rwxr-xr-x 1 root root 4.0G Oct 24 17:17 ptestv1-f7.img
# file ptestv1-f7.img
ptestv1-f7.img: x86 boot sector; partition 1: ID=0x83, active, starthead
1, startsector 63, 6120702 sectors; partition 2: ID=0x82, starthead 0,
startsector 6120765, 2040255 sectors, code offset 0x48
We installed Fedora 7 on the virtual machine, i.e., during the initial
process of adding the new machine. (We used Fedora 7 just because we
happened to have the distro on-line locally. At this point the whole
process is nothing more than an exercise.)
We got through the Fedora installation without any evident problems, but
when we hit the "Reboot" button at the end of the installation, that was
the last we saw of the virtual machine.
Now, when we open virt-manager and connect to "Local Xen host", we see
only Domain-0. If we go to the File menu, select "Restore saved
machine", and then specify the image indicated above (ptestv1-f7.img),
we get an error message from virt-manager:
Error restoring domain '/virt/ptestv1-f7.img'. Is
the domain already running?
In the terminal window from which we started virt-manager, we get the
following, additional error message:
# libvir: Xen Daemon error : POST operation failed: (xend.err
'Restore failed')
libvir: error : library call virDomainRestore failed, possibly
not supported
The system is fully patched, including the latest xen kernel (as of
yesterday, 2007-10-24), and has been rebooted.
Can anybody tell me what I'm doing wrong here, and/or tell me a better
approach? Thanks.
- Mike
