xen-netfront crash when detaching network while some network activity

2015-05-22 Thread Marek Marczykowski-Górecki
Hi all, I'm experiencing xen-netfront crash when doing xl network-detach while some network activity is going on at the same time. It happens only when domU has more than one vcpu. Not sure if this matters, but the backend is in another domU (not dom0). I'm using Xen 4.2.2. It happens on kernel 3.
