nat network hangs intermittantly
|Reported by:||dtgeorge||Owned by:|
|Guest type:||Windows||Host type:||Linux|
Host: Ubuntu 14.04 64Bit
Guest: Windows Server 2012, Windows XP - defect present for both guests.
Both guests are headless, used only by RDP.
Sometimes (1-2 times per day) guest network adapter stops to recieve any packets from "media", can't ping default gw for this network interface.
The only things that fix issue is nat network restart:
VBoxManage natnetwork stop --netname nat-int-network-2 VBoxManage natnetwork start --netname nat-int-network-2
Of course, may be there are another ways... reboot particular guest or perform "sudo /etc/init.d/vboxdrv restart" (requiring all VMs stop)... But the only way I found to fix issue (while not rebooting/stopping guest is restart nat network... I have two nat networks (192.168.1.0/24 and 192.168.2.0/24). They hangs indpendently:
- First one, nat-int-network (192.168.1.0/24), connected to WinXP guest (single network adapter within guest) hangs rarely - 1-2 times per month.
- Second one, nat-int-network-2 (192.168.2.0/24), connected to Windows Server 2012 Guest (one of two network adapters within guest, second one is openvpn tap0 interface attached to guest as Bridged Adapter) and hangs more often - 1-2 times per day... sometime 1 time per 2-3 days...
Windows Server guest is a loaded by 5-10 simultaneous RDP-sessions, but average load is quite moderate...
I understand that info provied is not enough. Please, let me know - what kind of details should I add to?
