[Xen-users] xen failed save - restore domain

[Lorenzo Verdini <lorenzo@xxxxxxxxxxxxxx>]

Hi all!

I have installed xen on fc6 with kernel 2.6.18-1.2798.fc6xen with rpm
package; i have create 3 guest os (fully virtualization) with
virt-manager tool, installed on separated partition:

1 fc6 guest, 1 centos 4.4, 1 windows xp pro; all work pretty fine until
this point, i have linked the configuration file of the guests machines
to /etc/xen/auto for autostart/autostop, but when shutdown the dom0 or
stop the guests os with the xendomains script this happens:

[root@xenhost ~]# service xendomains stop
Shutting down Xen domains: centos4.4(save)Error:

/etc/init.d/xendomains: line 299:  8581 Terminated

the same thing happens when I try to execute the "xm save" or "xm
restore" command:

[root@xenhost ~]# xm save winxp /tmp/try

Error: /usr/lib64/xen/bin/xc_save 20 21 0 0 0 failed
Usage: xm save <Domain> <CheckpointFile>

Save a domain state to restore later.
the system remains in execution and in the specified path there is the
file /tmp/try  of 796 kb
the other subcommand of xm work e.g.: xm pause, xm list, xm top
The configuraition file of guest vm is like this:

# Automatically generated xen config file
name = "centos4.4"
builder = "hvm"
memory = "256"
disk = [ 'phy:/dev/sdb1,hda,w' ]
vif = [ 'type=ioemu, mac=00:18:F3:67:FD:DF, bridge=xenbr0', ]
uuid = "fef4d4a4-e78e-84bd-8fd2-6b544f0c0380"
device_model = "/usr/lib64/xen/bin/qemu-dm"
kernel = "/usr/lib/xen/boot/hvmloader"
vnc=1
sdl=0
vncunused=1
apic=1
acpi=1
pae=1

vcpus=1
serial = "pty" # enable serial console
on_reboot   = 'restart'
on_crash    = 'restart'

anyone have a solution for this strange problem?
