Today I noticed that although I removed the membaloon it didn't stick (possibly due to panic not syncing the file). I removed once again membaloon and started the guest with little bit better results. The system does not freeze immediately, but it leaves a lot of oopses in the syslog/dmesg. I

In nat mode it does not panic. Having virtual machine in nat mode is piss poor, especially when the network performance in nat mode is very unreliable (perhaps issue with MTU? apt-get install gets stuck on 0% [Waiting for headers], wget google.com also hangs, while I can ping everything fine),

One thing I noticed that kernel panic comes much faster if there is network activity on the guest. Although I might be wrong... Anything else I could do? I will try to run guest without any network activity and see if it is panics. -- You received this bug notification because you are a member
