Yesterday I experienced a segfault on my vde_switch after 88 days working fine. VDE connects my qemu VMs together and is heavily in use. I want to report this to help you find problems and to ask if there is a possibility to restart the vde device after this fault and how this will affect my VMs.
I use the debian package (vde2, 2.3.2-4, amd64, Linux 3.2.0-4-amd64 #1 SMP Debian 3.2.46-1 x86_64 GNU/Linux), the log is as follows:
Dec 4 22:59:46 server kernel: [7847125.283822] vde_switch: segfault at 80 ip 0000000000404b48 sp 00007fffbd1339e8 error 4 in vde_switch[400000+15000]
Thank you and VDE is great!
