Hi,****
** **
I have the exact same problems with the latest 2.5.5-0.1.****
** **
**1.       **I’m unable to install from USB stick because after
installation, the system does not find it’s root volume.****
**2.       **Using a CDROM, the installation hangs. First time it hanged
at 75%. Second time I tried, it hanged at 25%. No message at all, but
keyboard is responsive (lock num, console switch).****
** **
I could try to do some debug for you. Having the root account used during
the installation would help. What is it?****
** **
With the CDROM installation, I’ve tried with 2 different hard drives and
the server was running fine with its previous OS, so no hardware issue here.
****
I was running the installation on a Poweredge 1950 server.****

Hi,
yesterday I tried the new oVirt Node 2.5.3. I tried installing it
without the quiet flag but no luck. It hanged again and the kernel
didn't show any error on console (tty2).
Later will test without the rhgh flag.****
Default options? TUI install? Hardware? UEFI or legacy bios?****
I always choose the troubleshooting option and then do an install with
basic video. The only thing I changed from the default kernel boot line was
the quiet flag.
Yes, TUI.
Hardware: this is an old MSI P35Neo MB with 4 GB RAM and a Xeon 3040. The
SATA disk is connected to the onboard controller. The same problem occurred
with an IDE HDD.****
Without rhgb and quiet no luck at all. Tomorrow will try with a SATA PCI
Card with a Sil chip.

BTW, now the hostname works on 2.5.3 :-) The network configuration is
still tricky... sometimes I have an "Apply" sometimes only a "Back"
choice.****
I *think* this is a feature of being registered to ovirt-engine.  Once
you are registered, you can't change the network through the TUI
anymore.
If you're not registered with Engine, please elaborate a bit and I'll
try to figure out what is going on.****
What you're saying makes sense. The problem I had was that my node was
booting with DHCP and the IP changed. When I got to the engine / web
administrator, my Host was not detected and I couldn't change it's IP, only
the hostname... On the TUI I can't change the IP because I'm registered but
can't change it also on the engine. Is this correct? ****

        It's working now :-)
Thanks a lot all!
Alex
P.S. I haven't tried installing it on my SATA disk because I
        have there a Local Node already running but I'm going to try
        again on another one to see if I can send to you the error
        log.

Glad it worked the second time.  There should be 4
                partitions on the
                disk.
Partition 1 is for UEFI or bios_boot depending on your
                machine type.
                Partition 2 and Partition 3 are Root and RootBackup.
                 So seeing a
                RootBackup is correct.  Not seeing a Root is
                incorrect.  If you rebooted
                the host in the middle of the install, or if the
                install hung for some
                reason, I can see that situation happening and see it
                working after
                uninstall/install.

You can't activate networking at all?  That is news to
                me.  The node
                should work perfectly fine with or without a FQDN.

Have you seen these issues with the 2.5.2 build?  Or
                only master branch
                builds?

I had the problem you mentioned about not finding the root volume. It's a
Fedora issue that you can solve on the boot, changing the root to /dev/sr0,
for instance.

About the setup hanging, I had a kernel panic (I think), because my
keyboard stopped responding.
