The "<seclabel type='dynamic' relabel='yes'/>" will cause error in libvirtd.log: From Bug 822589: Define a domain with xml: ... <seclabel type='dynamic' relabel='yes'/> ... # virsh start libvirt_test_api Domain libvirt_test_api started # virsh dumpxml libvirt_test_api check xml: ... <seclabel type='dynamic' relabel='yes'/> <seclabel type='dynamic' model='dac' relabel='yes'> <label>107:107</label> <imagelabel>107:107</imagelabel> </seclabel> <seclabel type='dynamic' model='selinux' relabel='yes'> <label>unconfined_u:system_r:svirt_t:s0:c39,c243</label> <imagelabel>unconfined_u:object_r:svirt_image_t:s0:c39,c243</imagelabel> </seclabel> ... After domain started, dac and selinux model seclabel are added, but the seclabel without model also stay. check in log: 2012-08-24 04:06:34.073+0000: 27164: error : virSecurityLabelDefParseXML:3129 : XML error: missing security model So the problem maybe due to that bug https://bugzilla.redhat.com/show_bug.cgi?id=822589. Michal fixed this problem in the following patch pushed upstream (in response comments in Bug 822589, which is tracking the addition of the new feature whose patches caused this regression): commit 0ee655f5f5ade7cb33e1f93af18c6948591d0fba Author: Michal Privoznik <mprivozn> Date: Fri Aug 24 14:59:59 2012 +0200 conf: Don't always require security/@model Only parse model, if static labelling, or a base label is set, or doing active XML. Verify this bug with libvirt-0.10.0-1.el6.x86_64. Update from 0.10.0-0rc0.el6.x86_64 to libvirt-0.10.0-1.el6.x86_64, the old guest still keep its status and no xml parse error. So move to VERIFIED. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

Description In libvirt-0.10.0-0rc1.el6, the guest xml parse is different from old packages. There is no xml parse error in old packages, but when upgrade packages, can not parse this element, give error in libvirtd.log, and there are guests can not be list with virsh list --all. version libvirt-0.10.0-0rc1.el6.x86_64 Steps 1. Install older package like libvirt-0.10.0-0rc0.el6.x86_64 2. define a guest like: # virsh dumpxml mig-0 <domain type='kvm'> <name>mig-0</name> <uuid>4926ef97-bbe3-b831-6dec-9611156ecdbf</uuid> <memory unit='KiB'>1048576</memory> <currentMemory unit='KiB'>1048576</currentMemory> <vcpu placement='static'>1</vcpu> <os> <type arch='x86_64' machine='rhel6.3.0'>hvm</type> <boot dev='hd'/> </os> <features> <acpi/> <apic/> <pae/> </features> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/libexec/qemu-kvm</emulator> <disk type='file' device='disk'> <driver name='qemu' type='raw' cache='none'/> <source file='/mnt/nfs/xxxx.img'> <seclabel relabel='no'/> </source> <target dev='hda' bus='ide'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> <controller type='usb' index='0'> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x2'/> </controller> <controller type='ide' index='0'> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x1'/> </controller> <controller type='virtio-serial' index='0'> <address type='pci' domain='0x0000' bus='0x00' slot='0x06' function='0x0'/> </controller> <interface type='network'> <mac address='52:54:00:f3:c5:2e'/> <source network='default'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> <serial type='pty'> <target port='0'/> </serial> <console type='pty'> <target type='serial' port='0'/> </console> <sound model='ich6'> <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> </sound> <video> <model type='cirrus' vram='9216' heads='1'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </video> <memballoon model='virtio'> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> </memballoon> </devices> <seclabel type='dynamic' relabel='yes'/> </domain> 3. Upgrade package to libvirt-0.10.0-0rc1.el6.x86_64 and check the libvirtd.log at the same time. 4. list guests # virsh list --all can not list the guest which has xml like above-mentioned. Actual result Get error like: # tail -f /var/log/libvirt/libvirtd.log ..... 2012-08-23 09:51:15.478+0000: 11413: error : virSecurityLabelDefParseXML:3129 : XML error: missing security model 2012-08-23 09:51:15.479+0000: 11413: error : virSecurityDeviceLabelDefParseXML:3230 : XML error: invalid security model ..... Expect result No error and works well. In addition, other packages are all working well using the same guest xml. So setting regression.
