High CPU usage

[Gray wolf]

I'm just getting into Proxmox and want to know more about it.

I installed it, created couple VMs already and so far so good. However, when I start the VM (ubuntu), the CPU is going crazy and not going down. Its usually above 90%.

I disabled the KVM and unchecked Ballooning but didn't help. Any ideas?

Btw, the basic specs are:

1 CPU
2GB ram
Display default

what CPU do you use? 2GB ram is also probably the bare minimum.

Inter I5 with 4 cores. Virtualization is also enabled. I tried increasing the ram to 3 GB but still no help.

What kind of storage do you use?

Can you tell me how to see that?

Can you tell me how to see that?

You probably use ext4/lvm if you don't know.

try running htop (install it first, apt-get install htop) or top, and you can see what is causing it.

I was more thinking of disk, storage server etc. If storage is slow this would influence CPU load.

It takes 10 minutes for OS to load and when it loads, its all black screen.

Also, how do I check the storage?

Anyone has an answer for me?

You must know what storage you selected during install. Is it local (some disks in this box) or networked? If local, is it zfs or lvm/ext? Anyway, 2 or 3GB is really not much for PVE. Your host might be swapping badly...

BTW I still think you'd better check "top". Either log-in to your PVE using ssh, or connect to web-interface and start console there. Default sort-list for "top" is by cpu-usage, so you can see what process is eating your cpu on top lines. Or you can create screenshot and post it here...
