Hi,
I just ran across these oddities when using a bit more libvirt+xen:
1.) virsh setmaxmem:
On a running domain:
# virsh setmaxmem domain 256000
completes but virsh dumpxml as well as the config.sxp still shows the
old amount of memory. Looks as the set_maxmem hypercall simply gets
ignored. xm mem-max works as expected. Smells like a bug in the ioctl?
2.) virsh list:
Sometimes (didn't find a pattern yet) when shutting down a running
domains and restarting it I'm seeing:
Id Name State
----------------------------------
0 Domain-0 running
2 foo idle
libvir: Xen Daemon error : GET operation failed: xend_get: error from xen daemon:
libvir: Xen Daemon error : GET operation failed: xend_get: error from xen daemon:
libvir: Xen Daemon error : GET operation failed: xend_get: error from xen daemon:
libvir: Xen Daemon error : GET operation failed: xend_get: error from xen daemon:
7 bar idle
Note that the number of errors the corresponds to the number of
shutdowns. VirXen_getdomaininfolist returns 7 in the above case.
virDomainLookupByID later on fails for these "additional" domains.
3.) virsh list: Duplicate domains:
Id Name State
----------------------------------
0 Domain-0 running
libvir: Xen Daemon error : GET operation failed: xend_get: error from xen daemon:
libvir: Xen Daemon error : GET operation failed: xend_get: error from xen daemon:
libvir: Xen Daemon error : GET operation failed: xend_get: error from xen daemon:
14 bar no state
libvir: Xen Daemon error : GET operation failed: xend_get: error from xen daemon:
16 bar idle
Domain 14 can't be shut down (xm list only lists domain 16).
Could be a similar problem as the above.
This is all libvirt 0.4.6 (but the code looks very similar in gurrent
CVS) and xen-3.2.1 on Debian. The detected ABI is hypervisor call v2,
sys ver6 dom ver5. And from a quick glance at the libxen-dev package the
structs seem to match.
Cheers,
