Hi All!

Just did more research on this and it seems as if the reason was related to my interface configuration. Disclaimer upfront: I've a public IP configured on this server (since it's a hosted root server), but changed the IP addr here to 192.168.0.99

I started with the output from ´vdsm-tool restore-nets':

ipv4addr, prefix = addr['address'].split('/')

ValueError: need more than 1 value to unpack

So I dumped the addr dictionary:

{'address': '192.168.0.99',

'family': 'inet',

'flags': frozenset(['permanent']),

'index': 2,

'label': 'eth0',

'prefixlen': 32,

'scope': 'universe'}

I've no clue why there's no "/32" at the end, but that's what my netmask actually is due to the special configuration I got from my hosting provider:

[root@vhost1 ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

BOOTPROTO=none

ONBOOT=yes

HWADDR=00:52:9F:A8:AA:BB

IPADDR=192.168.0.99

NETMASK=255.255.255.255

SCOPE="peer 192.168.0.1"

(again, public IPs changed to private one, if that matters. And I skipped the IPv6 config above...)

So what I did next, was to patch the netinfo.py:

[root@vhost1 vdsm]# diff -u netinfo_orig.py netinfo.py

--- netinfo_orig.py 2014-12-24 22:16:23.362198715 +0100

+++ netinfo.py 2014-12-24 22:16:02.567625247 +0100

@@ -368,7 +368,12 @@

if addr['family'] == 'inet':

ipv4addrs.append(addr['address'])

if 'secondary' not in addr['flags']:

- ipv4addr, prefix = addr['address'].split('/')

+ """Assume /32 if no prefix was found"""

+ if addr['address'].find('/') == -1:

+ ipv4addr = addr['address']

+ prefix = "32"

+ else:

+ ipv4addr, prefix = addr['address'].split('/')

ipv4netmask = prefix2netmask(addr['prefixlen'])

else:

ipv6addrs.append(addr['address'])

and recompiled it:

[root@vhost1 vdsm]# python -m py_compile netinfo.py

Et voilà:

vdsm-tool ran fine:

`hosted-engine --deploy' passed the previous failing stage!

Hope this helps to find the root cause....

Regards,

Andreas

Hi All!

Just tried to install the hosted engine on a fresh CentOS 6.6: beside setting up a gluster cluster, I just added the repo and installed hosted-engine-setup package. Otherwise it's just a very minimal installation. hosted-engine deploy failed immediately. The issue seems to be the same as described here http://lists.ovirt.org/pipermail/users/2014-October/028461.html but that conversation didn't continue after the reporting user was asked for additional details.

Failed installation:

[root@vhost1 ~]# hosted-engine --deploy
