Hi all,
I have some problem with xm save/restore in Xen-4.0.0 & linux-2.6.31.13,
First, the /etc/init.d/xendomains seems do not work properly because of bash
version. So I modified it as follow:
root@r02k08027 # diff -up /etc/init.d/xendomains /etc/init.d/xendomains_31
--- /etc/init.d/xendomains 2010-04-08 00:12:04.000000000 +0800
+++ /etc/init.d/xendomains_31 2010-04-19 22:45:35.000000000 +0800

id=$(echo $1 | sed -e ''s/^.*(domid \(.*\))$/\1/'')
fi; fi; fi
Then service xendomains start/stop works correctly. But there is a
significant problem. I tried to save and restore these VMs:
redhat-4.6-32bit with pv driver, redhat-4.6-32bit without pv driver;
WindowsServer2003-32bit with pv driver (Xenpv-win-32bit-0.97.4.exe),
WindowsServer2003-32bit without pv driver;
WindowsServer2008-64bit with pv driver (Xenpv-win-64bit-0.97.4.exe),
WindowsServer2008-64bit without pv driver.
Others are OK, only redhat-4.6-32bit domain with pv driver failed. But this
VM is the most important for me. When saving it, it blocks, the size of the
saved file is always 1.8K:
-rwxr-xr-x 1 root root 1.8K Apr 17 19:08 redhat-4.6-32
The error xend.log report is:
DEBUG (XendCheckpoint:124) [xc_save]: /usr/lib64/xen/bin/xc_save 4 3 0 0 4
INFO (XendCheckpoint:423) xc_save: failed to get the suspend evtchn port
The pv driver of redhat-4.6-32bit are:

Is there anyone can give me a good idea?
I’ll try another version of pv driver or another version of redhat…
Thanks
