xen/libvirt freeze while attching network-device to vm´s
...20 to 100 cycle. Their are no error-messages, no crash,
noting in "dmesg" or "xl dmesg".
When i attached to the libvirtd via gdb and do a "info thread", i get

Bingo! So we've a deadlock here. Somebody has forgotten to unlock a
domain. So as we go over the domain list...

deadlock on connection loosing
libvirtd will lock if for example kill programm which established connection,
only sigkill + restart helps., to reproduce:
virConnectPtr libvirt_connection = virConnectOpen("qemu:///system");
if(libvirt_connection == NULL)
{
std::cout<<"failed to connect to qemu:///system\n";
exit(-1);
}
exit(0);

error : virHashForEach:597 : Hash operation not allowed during iteration
Hey!
On many of our servers, we often have the following error:
error : virHashForEach:597 : Hash operation not allowed during iteration
When querying the list of domains, this means libvirt will silently
return 0 domain (most uses of virHashForEach don't handle the return
code).
We are using a hook, but the hook doesn't query libvirt back, so it
should be safe from this point of view.
