Based on Daniel's feedback I did a split for public/private functions
for those that cause the lockup when getting XML. Maybe not complete
but at least seems to allow basic usage again (through virt-manager).

Subject: [PATCH] xen: Use internal interfaces in xenDomainUsedCpus
Since commit 95e18efd most public interfaces (xenUnified...) obtain
a virDomainDefPtr via xenGetDomainDefFor...() which take the unified
lock.
This is already taken before calling xenDomainUsedCpus(), so we get
a deadlock for active guests. Avoid this by splitting up
xenUnifiedDomainGetVcpusFlags() and xenUnifiedDomainGetVcpus() into
public and private function calls (which get the virDomainDefPtr passed)
and use those in xenDomainUsedCpus().
xenDomainUsedCpus
...
nb_vcpu = xenUnifiedDomainGetMaxVcpus(dom);
return xenUnifiedDomainGetVcpusFlags(...)
...
if (!(def = xenGetDomainDefForDom(dom)))
return xenGetDomainDefForUUID(dom->conn, dom->uuid);
...
ret = xenHypervisorLookupDomainByUUID(conn, uuid);
...
xenUnifiedLock(priv);
name = xenStoreDomainGetName(conn, id);
xenUnifiedUnlock(priv);
...
if ((ncpus = xenUnifiedDomainGetVcpus(dom, cpuinfo, nb_vcpu,
...
if (!(def = xenGetDomainDefForDom(dom)))

libvirt typically uses a '*Internal' naming pattern for these types of
internal functions, e.g. xenUnifiedDomainGetVcpusFlagsInternal. Also as
we touch this code we should strive to use the libvirt pattern of
putting each parameter after the first on a new line when the list of
parameters exceeds 80 columns. Finally, since you added a line after
the xenUnifiedNodeGetInfo declaration, we should add one here too.

Absolutely right. I missed to do that in the version I forward ported to HEAD
since I did the fix and testing in an older version. :/
Good you spotted that.
Ok, I updated the patch as suggested (attached).
