Infrastructure Software

I created a couple of OL6-U3 PVM's on a SuSE-Xen host (using virt-install) and manually migrated the VM's to my OVS-Xen host. The migration was successful. However, the VM's aren't persistent. i.e., the VM's won't survive a reboot:

[root@xen3 ~]# xm list
Name                                        ID   Mem VCPUs      State   Time(s)
Domain-0                                     0   568     2     r-----  34467.9
oracle1                                      1   786     1     -b----     58.2
oracle2                                      3   786     1     -b----     58.2

[root@xen3 ~]# xenstore-ls | grep '   name ='
   name = "Domain-0"
   name = "oracle1"
   name = "oracle2"
   name = "Pool-0"

[root@xen3 ~]# xm shutdown oracle1
[root@xen3 ~]# xm shutdown oracle2

[root@xen3 ~]# xm list
Name                                        ID   Mem VCPUs      State   Time(s)
Domain-0                                     0   568     2     r-----  34564.1

[root@xen3 ~]# xm start oracle1
Error: Domain 'oracle1' does not exist.

I've noticed that there aren't any configuration files in /etc/xen:

[root@xen3 ~]# ls -1 /etc/xen
auto
cpupool
README
README.incompatibilities
scripts
xend-config.sxp
xend-pci-permissive.sxp
xend-pci-quirks.sxp
xl.conf
xm-config.xml
xmexample1
xmexample2
xmexample3
xmexample.hvm
xmexample.hvm-stubdom
xmexample.nbd
xmexample.pv-grub
xmexample.vti
[root@xen3 ~]# ls -1 /etc/xen/auto/

...and that if I try the method recommended in Chapter 5.3, Configuring a Virtual Machine by Modifying its Xend Settings, of the SuSE manual Virtualization with Xen, Xend complains:

[root@xen3 ~]# xm new -F ~/oracle1.cfg 
Unexpected error: exceptions.ImportError

How can I make these VM's persistent?
list [OPTIONS] [domain-id ...]
Prints information about one or more domains. If no domains are specified it prints out information about all domains.

OPTIONS

-l, --long
The output for xm list is not the table view shown below, but instead presents the data in SXP format.
