Installation is OK with USB.
The problem I have with USB install is when installation is finished and I want to use my node, the root FS (or any required FS) is not found.
So the problem I have is not related to the problem you link.
What's more my /dev/sda is not alone. I have 4 partitions : sda1,sda2,sda3,sda4. I'll try to boot from a live Linux to get a complete environment (device mapper, LVM, etc ...) to see what's going wrong because currently the Dracut env is very poor.
With CDROM installation, I have waited hours ( I had lunch during installation). No kernel panic, and sufficient time to complete.

Hi,
The installation I did from USB was targeted to hard drive.
I can see that installation creates 4 partitions (/dev/sdaX), but I don't know which one is the root volume, and LVM may be used. For sure I don't want to boot from CDROM (sr0) but from my local hard drive (/dev/???).
Regarding CDROM installation, with the version I used (the latest), I'm able to switch the consoles when installation hang. Does not look like a kernel panic, but there is a real problem.
Again, having the root account used would help, if someone can provide it...
Vince

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.

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.

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?

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.

The use of /dev/sr0 is intended to be only on install. After installation it would boot to /dev/sda or /dev/mapper/by-Name...

If you can change consoles, it should be still running. For how long have you waited?
