Hi

I'm having some trouble with proxmox 1.4
I managed to get firefox working with vnc console for openvz but when i do a vnc to a kvm machine firefox just freezes.

Also when i start the kvm machine the cpu goes within 10 sec after start to 98% / 100% without doing anything.
I know that the machine has VT, i just enabled it.
I tried IDE, removing cdrom and floppy etc..

When i go to options and disable KVM, the cpu stays at 0% and also when i do a "freeze cpu at startup".

Anyone a idea? openvz works fine but KVM just has to work:(

The vnc console works perfectly here - what java version do you use?

When you start a VM it starte the VM Bios - which normally using 100% CPU until the real OS starts.
 
So is the java version ok? what can i do to resolve the freezing firefox problem when i use vnc to manage kvm machines?

for VNC console, the version is ok, but I assume its a problem on your desktop. to validate, access the vnc console from another PC (and also another browser on the same)

does the VNC console works for containers? if yes the issue not VNC, its KVM on your Proxmox VE host.
 
Well vnc does work with openvz container.
It is only the kvm vnc that freezes, any idea's ?

VT is supported.

so VNC works. and KVM not, as far as I see.

  • did you poweroff your server after enabling VT (this is needed to activate VT)?
  • do you run the latest motherboard bios?
  • to make sure that you run the latest version, run 'apt-get update' and 'apt-get dist-upgrade'
if you have no success: what cpu/mainboard combination do you use?
 
- Well i did a reboot(unplugged power cord) after VT enabling in bios.
- I didn't do a bios flash.
- I did do a apt-get update upgrade and dist-upgrade

After the dist-upgrade de KVM machines cpu didn't go to 100% anymore, now it stayes at 0% a peak of 6% but mostly 0%
And the vnc still freezes after a couple of seconds.
It does say: Connected to <ip addr>... but noting more....

I have:
Intel S3000AHLX
Core 2 duo 2.4Ghz - E6600
8Gb of ram ECC and 4 x Sata 250Gb Raid 5 with a 3ware raid controller

This is a test machine, but if i want to use proxmox ve what machines are supported?
I prefer a HP rackserver so if there are known good working types please let me know.
 
I managed to get to the kvm console by external VNC:

nc -l -p 5900 -c "qm vncproxy VMID PASSWORD"

But that is not the normal way i think...

so you have it working with the external VNC? means KVM is working and its just the VNC browser plugin?

you are right, that's not expected. there are thousand of Proxmox VE servers where it works with the VNC browser plug in.

try another browser and/or access from another PC.
