Odd. 'save' is a very simple special case of 'migrate'. Migrate
has been tested loads recently, but I guess that 'save'
hasn't. It's so simple, how could it break? ;-)

Does 'ps auxw' show an 'xfrd' running?

Does 'xend restart' help?

What happens if you do an 'xm migrate VMID localhost' ?

Is xfrd running at this point? Is xfrd installed as /usr/sbin/xfrd?
Is there a pid recorded in /var/run/xfrd.pid?

Hi,

Thanks for the fast reply, and sorry about my delay.

xfrd wasn't running. I tried to start it, but there are some libs
missing. I am running a slackware 10 install.

# ldd xfrd
libxc.so.1.3 => /usr/lib/libxc.so.1.3 (0x4002c000)
libxutil.so.1.3 => /usr/lib/libxutil.so.1.3 (0x40039000)
libz.so.1 => /usr/lib/libz.so.1 (0x4003c000)
libcurl.so.2 => /usr/lib/libcurl.so.2 (0x4004d000)
libssl.so.4 => not found
libcrypto.so.4 => not found
libgssapi_krb5.so.2 => not found
libkrb5.so.3 => not found
libk5crypto.so.3 => not found
libcom_err.so.3 => not found
libresolv.so.2 => /lib/libresolv.so.2 (0x40078000)
libdl.so.2 => /lib/libdl.so.2 (0x4008a000)
libc.so.6 => /lib/libc.so.6 (0x4008d000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
libssl.so.0 => not found
libcrypto.so.0 => not found

Looks like slackware 10 doesn't come with kerberos5. So I downloaded
it, and the latest openssl. I had to create some links manually:

libcom_err.so.3 -> libcom_err.so
libcrypto.so.0 -> libcrypto.so.4
libcrypto.so.4 -> libcrypt.so
libssl.so.0 -> libssl3.so
libssl.so.4 -> libssl3.so

After that, the xfrd started along with xend. And the xm save VMID
FILE worked. But when I tried the xm restore FILE, Xen created a new
VM, but didn't load the memory back (I know because of no HD activity
after the command), and didn't return from the xm restore command.
Logging into another console, and issuing xm list:

Name Id Mem(MB) CPU State Time(s) Console
Domain-0 0 123 0 r---- 219.0
Domain-8 8 64 0 --p-- 0.0

The Domain-8 name shows that Xen didn't restore the previous VM's info
(the name was something else).

Any ideas? (besides changing the distro)
