Hi Stefano
Here is some xl related bugs which opened for long time and I didn't see anyone working on them. I retest them with latest xen upstream and all of them are still exist.
1. [XL]Fail to create multi-guests with NIC assigned
http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1761
xm don't have the issue.
2. [XL]Guest network broken after do SAVE/RESTOR with xl
http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1703
I never pass this case after using xl.
3. [XL]"xl vcpu-set" causes dom0 crash or panic
http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1730
This is a regression which I found during Xen 4.1 release cycle testing.
4. [XL]device reset fail when create/destroy guest
http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1752
This is not a critical bug. But the warning is boring.
If you need more information about those bugs, please let me know.
best regards
yang

My test system does this and it works. That is, it does save/restore
tests of guests and checks that the guest is working afterwards by
talking to the guest over the vif.

from the logs:
*** glibc detected *** xl: malloc(): memory corruption (fast):
it appears to be triggered by libxl_domain_create_new.
Could you please add some more debug messages to xl and libxl to find
out exactly what causes the memory corruption?

This one is pretty bad. Konrad, I have the feeling somebody else
reported a similar bug recently...

I did. But I think you fixed it initially, and then later on tglrx
accepted the patch to fix this for good in generic.
I can't reproduce it anymore on 2.6.39.

I thought it was that bug, I am glad is gone. We should probably submit
one of the two fixes to Jeremy's tree.

Weird, I seem to have something similar happening now that I updated my
Ubuntu 11.04 box (apt-get update).

False alarm. Had the libxen* in /usr/lib and /usr/lib64 and they were both different
versions.
