[ovirt-users] getting 404 after fresh install of oVirt 3.4 on CentOS 6.5 (+ solution)

[Steven Van Acker]

Hello all,

I was asked to post the following problem on this mailinglist.

After installing a clean CentOS 6.5 with a clean oVirt 3.4, following the
instructions from
http://www.ovirt.org/Download#Red_Hat_Enterprise_Linux_6.2FCentOS_Installation_Instructions
I went to http://localhost.localdomain:80/ovirt-engine as indicated and was
redirected to a 404 page. The same happened when using https.

During the installation, engine-setup will print out the following on my VM
with 512MB RAM:

[WARNING] Warning: Not enough memory is available on the host. Minimum
requirement is 4096MB, and 16384MB is recommended.
          SSH fingerprint: 4B:DE:48:26:99:AA:C0:72:E3:C8:B5:64:5F:6E:6D:00
          Internal CA
FB:82:FE:14:35:3A:BE:1A:B1:E6:99:C2:DC:CD:6D:E0:44:64:0F:47
          Web access is enabled at:
              http://localhost.localdomain:80/ovirt-engine
              https://localhost.localdomain:443/ovirt-engine
          Please use the user "admin" and password specified in order to
login into oVirt Engine

The consequence of not having enough RAM for oVirt is that it will silently
fail to start up, without apparent errors or warnings.
In my view, the warning above should be rephrased as "Not enough memory is
available on the host, oVirt will refuse to start" and colored red.

The solution to this problem is to have at least 4GB of RAM, after which
oVirt seems to start up fine (with only 1.2GB of RAM in use).

kr,
