Hi,

well it turns out I'm happy to _not_ have already upgraded to 3.4. because I heavily rely on vlans.

revisiting http://www.ovirt.org/OVirt_3.4_release_management

I see the following criteria:

MUST: vm life-cycle is working flawlessly (start,suspend,resume,stop,migrate)

MUST: Can define VLAN based networks, bond interfaces, and have VLANs over bonded interfaces

however it seems that the combination of both of these features didn't get tested.

I therefore suggest to add a new "MUST" to the VLAN based networks:

MUST: vm life-cycle is working flawlessly (start,suspend,resume,stop,migrate) with VLANs

what do you think?

I think that this is an unfortunate bug that creeped into ovirt-3.4.0. However, please that note that it does not affect the plain network definitions described in the release criteria, but rather a more complex one, that includes QoS support. Since it's creating too much grief, I'm inclined to ask Douglas if he could rebuild vdsm for el6 and Fedora with that single patch added to it. Can this be done?

Thanks a lot for the information! Good to know that this is already known and will get fixed. Didn't recognize your thread - already too many mails on this list :) Regards, René

Hi,

I configured Network QoS in my oVirt 3.4 setup, but can't start vms.

Here are the steps I did: - Create QoS in Data Centers - Network QoS tab (Name: testing, limits: 10/10/100, 10/10/100) - Add QoS to vNIC Profile using Networks - vNIC Profile - edit

When I try to start a vm the following error is shown in vdsm.log:

Thread-837844::ERROR::2014-04-__14 12:45:51,822::vm::2289::vm.Vm:__:(_startUnderlyingVm) vmId=`d7034850-c274-48f7-ac0f-__b3d4cc57c255`::The vm start process failed Traceback (most recent call last): File "/usr/share/vdsm/vm.py", line 2249, in _startUnderlyingVm self._run() File "/usr/share/vdsm/vm.py", line 3135, in _run domxml = hooks.before_vm_start(self.___buildCmdLine(), self.conf) File "/usr/share/vdsm/vm.py", line 2965, in _buildCmdLine self._appendDevices(domxml) File "/usr/share/vdsm/vm.py", line 2922, in _appendDevices deviceXML = dev.getXML().toxml(encoding='__utf-8') File "/usr/lib64/python2.6/xml/dom/__minidom.py", line 45, in toxml return self.toprettyxml("", "", encoding) File "/usr/lib64/python2.6/xml/dom/__minidom.py", line 59, in toprettyxml self.writexml(writer, "", indent, newl) File "/usr/share/vdsm/vm.py", line 5268, in __hacked_writexml node.writexml(writer, indent + addindent, addindent, newl) File "/usr/share/vdsm/vm.py", line 5268, in __hacked_writexml node.writexml(writer, indent + addindent, addindent, newl) File "/usr/share/vdsm/vm.py", line 5256, in __hacked_writexml xml.dom.minidom._write_data(__writer, attrs[a_name].value) File "/usr/lib64/python2.6/xml/dom/__minidom.py", line 301, in _write_data data = data.replace("&", "&").replace("<", "<") AttributeError: 'int' object has no attribute 'replace' Thread-837844::DEBUG::2014-04-__14 12:45:51,826::vm::2731::vm.Vm:__:(setDownStatus) vmId=`d7034850-c274-48f7-ac0f-__b3d4cc57c255`::Changed state to Down: 'int' object has no attribute 'replace'

When removing the QoS (or better say put it to unlimited) my vm is starting fine.

My host is running CentOS 6.5 with latest updates.
