[ovirt-users] hosted-engine --deploy stalls on "Waiting for VDSM hardware info"

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hi, I've been running oVirt 3.6 on Fedora 22 for a while now, as a two node set up, and everything was going fine until I decided to upgrade from Fedora 22 to 23 (as 22 is pretty much EOL). That didn't go exactly to plan, so to minimise any issues moving forward I did a complete new install of Fedora 23 on one of the hosts, with a view to just importing the back up from the 3.6 system. The issue I'm running into at the moment is that when I run hosted-engine --deploy (hosted engine setup obviously) on the new host, the process gets to "Waiting for VDSM hardware info", repeats that for a while and then fails out of the set up. I've pinned it down to the following not returning the expected information: vdsClient -s 0 getVdsHardwareInfo This returns "Failed to read hardware information" rather than the expected information. Running this same command on the Fedora 22 system returns hardware information, even installing 3.6 on the new system returns the same error. I'm presuming it's not a specific oVirt issue, but down to some dmidecode (or related) issue. Running the above, rather than hosted-engine --deploy gives the following as the last entry in supervdsm.log MainProcess|jsonrpc.Executor/2::DEBUG::2016-07-08 08:08:04,377::supervdsmServer::92::SuperVdsm.ServerCallback::(wrapper) call getHardwareInfo with () {} MainProcess|jsonrpc.Executor/2::ERROR::2016-07-08 08:08:04,409::supervdsmServer::96::SuperVdsm.ServerCallback::(wrapper) Error in getHardwareInfo Traceback (most recent call last): File "/usr/share/vdsm/supervdsmServer", line 94, in wrapper res = func(*args, **kwargs) File "/usr/share/vdsm/supervdsm_api/hwinfo.py", line 29, in getHardwareInfo return getHardwareInfoStructure() File "/usr/lib/python2.7/site-packages/vdsm/utils.py", line 465, in __call__ value = self.func(*args) File "/usr/lib/python2.7/site-packages/vdsm/dmidecodeUtil.py", line 52, in getHardwareInfoStructure dmiInfo = getAllDmidecodeInfo() File "/usr/lib/python2.7/site-packages/vdsm/utils.py", line 465, in __call__ value = self.func(*args) File "/usr/lib/python2.7/site-packages/vdsm/dmidecodeUtil.py", line 46, in getAllDmidecodeInfo myLeafDict[k] = __leafDict(getattr(dmidecode, k)()) File "/usr/lib/python2.7/site-packages/vdsm/dmidecodeUtil.py", line 34, in __leafDict ret.update(__leafDict(v)) File "/usr/lib/python2.7/site-packages/vdsm/dmidecodeUtil.py", line 34, in __leafDict ret.update(__leafDict(v)) File "/usr/lib/python2.7/site-packages/vdsm/dmidecodeUtil.py", line 32, in __leafDict for k, v in d.iteritems(): IndexError: list assignment index out of range Running dmidecode manually appears to return the same information an almost identical system returns (Dell R710). Any pointers on tracking down what the issue might be as I'd rather not reinstall with 22 again just to get this up and running. Regards Alex.
