[one-users] VPN Access ...

Wed Aug 15 00:53:43 PDT 2012

Hi,

Well the guest OS is a simple ubuntu 12.04.iso, which was recently downloaded. Indeed the same guest OS was mounted and installed using virt-manager without any problem. I'll figure out where it is the problem.

Cheers,
Héctor

Hi

This seems to be a wrong installation of the guest OS, it is either missing some modules to mount the FS or the disk does not have a valid OS installation. As far as it seems there is no error from the OpenNebula point of view...

Cheers

Ruben

Well I now get a different error:

-No filesystem could mount root, tried: ext3 ext4 fuseblk
-Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block (8,1)

I also attached a png file with the mentioned error.

Cheers,
Héctor

Hi Daniel,

Could you try specifying the ROOT device in the OS section?

OS=[
  ARCH="x86_64",
  BOOT="hd",
  ROOT="sda1" ]

Cheers

On the other hand I verified the oned.conf file which is enclosed in this mail, and I didn´t find any mistake.

Thanks in advance,

Cheers,
Héctor

Hi all,

I created a Ubuntu 12.04 LTS virtual machine to test my OpenNebula installation and I got some errors when sunstone tries to connect to it using VNC.

VFS: cannot open root device ¨(null)¨ or unknown-block(0,0)
Please append a correct root¨ boot option; here are the available partitions:
0800    715052         sda driver: sd
0801    715020         sda1
0b00    1048575       sr0 driver: sr

Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block (0,0)

Did you get these errors before ? I think I need to configure something at the BOOT parameters of my virtual image template but I don´t know what.

I also attached a png file to show you the error.

Could you send us the template you're using? and please check if there is any error in your oned.log

Cheers.

Thanks in advance.

Best,
Héctor
