Re: [ovirt-users] Hosted Engine 4.0.1 GUI takes long time to be available after Engine start

[Scott]

Hi Matt,

I noticed a similar issue with oVirt 4.0 that I did not see in 3.6.  In
this particular environment, I don't run the DNS resolvers so I can't speak
to as whether that was a problem at the time (I doubt it, but you never
know).

One thing that seemed to help for me was to increase available entropy.
The value in /proc/sys/kernel/random/entropy_avail on my hosted engine VM
was very low (like ~135).  To do this, I used haveged, since its not
possible to attach the virtio-rng device to the HostedEngine VM (hopefully
this changes in a future release).  After this, my available entropy
approaches 4096 (the default target in haveged).  I can't say for certain
this was the sole cause/effect, but it certainly seemed to help.

Hi,

I could be Rdns at the moment as I'm having strange Virtio issues on
4.0, nics are doing strange on Linux VM's ??

If it's started it's just fine and fast

I will update this thread when DNS is up again as I needed to
reference this a little but... at the other end... I thought it
happened also with DNS running... need to check.

Thanks so far!

No, it's not known. If you are sure there are no DNS and reverse DNS
issues, I'd be happy if you could share engine.log and server.log from the
engine VM.
