Red Hat Bugzilla – Bug 428879
Libvirt lacks xml escaping for xm config parsing
Last modified: 2009-12-14 16:23:09 EST
If you manually edit an xm config file to add a disk path containing the '&'
character, virt-manager and virtinst start dumping lots of errors like:
Entity: line 14: parser error : xmlParseEntityRef: no name
Since 'xm create' works fine with this config file and an '&' is a valid
character to have in a path, this seems like a bug.
See also bz 428209 for a similar bug.
# rpm -q libvirt
Still current, trivial to reproduce:
[root@test2 ~]# grep test /etc/xen/migr5
disk = [ "tap:aio:/virt/migr5&test,xvda,w" ]
[root@test2 ~]# virsh dumpxml migr5 | grep source
we need to XML escape path strings in the xm driver. This should not be
too hard, assuming it's not fixed already upstream.
