Antwort: Re: [xenpreview-dev] Problems with save / restore of domUs

[tobias.mucke at man.eu]

Hi,

I updated to the newest changeset and save / restore / migrate is working
fine now. Also under heavy load. We are migrating an Oracle domU
permanently back and forth since some days while an Oracle benchmark is
running in it. A permanently running ping says that only 3% of pings are
lost.

Unfortunately testing showed up a new issue. Save and Restore on the same
Xen system works fine. Machine is pingable afterwards again. But save /
restore / migrate to another Xen system in the Xen cluster leads to a not
pingable domU, since I ping from within the domU into our network. Is this
an ARP issue? For our testenvironment above I worked around it pinging
always from within domU.

We tested save / restore / migrate also with Xen 3.0.2 GA with SLES-10 and
domUs were reachable fine afterwards. But we discovered a kernel Eeek in
3.0.2 so we upgraded to XTP.

Thanks, again.

Tobias
