Ticket Resolution Summary Owner Reporter
#1794 fixed Host hibernation hang after runing Virtual Box with enabled VT-x -> fixed in SVN/2.2 Zoltan Fekete
Description

Similar to ticket #1408.

Host PC: Notebook HP 9710p, Intel Core 2 duo processor, Windows XP Professional SP3, latest version of Virtual Box (1.6.2).

If any guest machine is run with hardware virtualization on (VT-x/AMD-V enabled), the host PC fails to enter hibernation (even after shutting down all of the guest machines and closing Virtual Box). The symptoms are: Start > Shutdown, hibernate, the OS displays "Preparing to hibernate... " message, then the screen goes black and nothing happens. I tried to wait for 15 minutes and nothing happened, only thing to do at this moment is to power off the notebook and power on again.

If the guest machines are run using software virtualisation only (VT-x/AMD-V disabled) everything works fine, and the host PC is able to hibernate.

Tried with different guest machines, Windows XP SP2, Ubuntu, etc., all behaving the same way.

#1797 fixed won't open host network interface => change TAP group setting Andrew Schulman
Description

I have the dreaded "Failed to open host network interface" problem. I'm using Host Interface networking on a Linux host (Debian AMD64, custom 2.6.24 kernel), with a tap device named vbox0 bridged to lan:

$ brctl show lan
bridge name     bridge id               STP enabled     interfaces
lan             8000.00161711ac84       no              lan0
                                                        vbox0

When user andrex tries to start the VM, it fails with the following VBox.log:

andrex is a member of the group vboxusers, which has read/write permission on /dev/net/tun:

$ ll /dev/net
total 0
crw-rw---- 1 root vboxusers 10, 200 2008-06-15 14:52 tun

A few other data points:

  • I tried chmod 0666 /dev/net/tun, but it didn't help.
  • root can run this VM, but no other users can AFAICT. So it sure seems like a permission problem, but permissions on interfaces and bridges are hard to debug since they apparently only live in kernel memory. syslog and kern.log provide no useful information.
  • This VM used to work fine with the same configuration. I upgraded my kernel a few weeks ago, and probably upgraded some system tools around the same time, and now I can't get past this problem.

Any help would be much appreciated, as I'm currently dead in the water with this VM. NAT networking isn't an option because it doesn't allow me to read Samba shares.

Thanks, Andrew.
