Virtual Machine install problem

I’ve never used;

Also it sounds like that you don’t have much experience with Virtual machines.

The first screen shot of QEMU/KVM appears to be problems regarding your Virtual Computer configuration.

Just to explain, the “It’s running” message is regarding the virtual hardware to run your machine is switched on.

Hence you have not installed anything regarding Rockstor.

Also please see the posts about installing on OpenSUSE

Since you are new to Virtual machines, Find a guide about installing OpenSUSE as a VM on your box.
Once that is working, follow the instructions on the two forum posts linked to get it going. (Otherwise you could wait a few weeks until the new Open SUSE installer ISO is ready)
