UMC/system setup fails to start on slow systems
Last modified: 2019-01-03 07:18:40 CET
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.

Otherwise UMC will fail as you've seen. *** This bug has been marked as a duplicate of bug 36837 ***
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: Connection to module process failed '''
