Running VM causes host networking to drop out

[Haggles]

Hi there, I'n not sure if this is a VM issue or OS. But here goes...

I'm running an Openindiana host with Virtualbox, but it now seems to have developed an issue. If I run just the host everything is stable, but if I run the guest (headless or through the GUI) after a while - could be a 30minutes, could be 12 hours - the host network drops out.

The only way I can get it back is to login to the box directly and reboot it.

If I run a netstat -i before the network drops out it get:

haggles@OIserver:~$ netstat -i
Name  Mtu  Net/Dest      Address        Ipkts  Ierrs Opkts  Oerrs Collis Queue 
lo0   8232 loopback      OIserver       308787 0     308787 0     0      0     
vboxnet0 1500 192.168.56.0  192.168.56.1   0      0     271    0     0      0     
e1000g0 1500 SUNW-i86pc-68-05-ca-24-6b-67.home SUNW-i86pc-68-05-ca-24-6b-67.home 171490 0     283758 0     0      0     

Name  Mtu  Net/Dest                    Address                     Ipkts  Ierrs Opkts  Oerrs Collis
lo0   8252 OIserver                    OIserver                    308800 0     308800 0     0     
e1000g0 1500 default                     ::                          171490 0     283758 0     0

But after the network drops I just get:

haggles@OIserver:~$ netstat -i
Name  Mtu  Net/Dest      Address        Ipkts  Ierrs Opkts  Oerrs Collis Queue 
lo0   8232 loopback      OIserver       101654 0     101654 0     0      0

I've tried googling around to no avail, any ideas?
Thanks

Not exactly sure what Openindiana is, but virtual box tends to create networkin issues. What is the IP Range of your physical network? Is it in same Subnet as your virtualbox networking? You should also look into KVM.

What is your network card type/emulation in Vbox?

 

[danswartz]

openindiana is an opensolaris derivative.

Thanks for your replies

My physical network is a normal 192.168.1.x range 255.255.255.0 subnet.
the host is .100 , the guest VM is set as static IP of .101

As for the VirtualBox settings; it's set as bridged adapter, adapter type is 'Intel PRO/1000MT Desktop' but I have also tried it with the virtio-net

Physically the host has an Intel 1000CT card installed (should I have a dual nic card so both the host and guest use their own port?)

Cheers
