Description Jürn Brodersen univentionstaff 2016-06-08 14:14:17 CEST
The UCS installation wizard doesn't load if qemu is used for virtualization. The debian installer does work.

qemu-system-x -cdrom ~/Downloads/UCS-Installation-amd64.iso -boot order=d -drive file=ucs41.img

Using the vmware image in qemu doesn't work either.

qemu-system-x -> qemu-system-x86_64

You MUST specify a network interface; at least one working interface is required for UCS. Otherwise UMC will fail as you've seen.

Comment 7 Jürn Brodersen univentionstaff 2016-10-06 20:16:17 CEST
I looked into this again:
The network interface was not the problem, qemu does add one by default. But qemu does not use a hypervisor by default resulting in a really slow vm.

There is a timeout for loading modules (around 10s) and loading the setup modules just took to long, resulting in an error. I don't know where that timeout is set.

Using "-enable-kvm" solves the problem.

It would be nice to have a better error message for slow systems. Or maybe even some sort of system benchmark.

Here is the error message in text form so that this bug is easier to find:
'''
 An error occurred

Internal server error: Could not connect to the module process.

Server error message:
