kvm crashed with SIGSEGV in malloc_consolidate() Binary package hint: kvm See Bug #355401. Oddly enough, when Windows tries to install drivers for a WDM device (a W380a on USB), kvm crashes.

Can you give me any hints about what's going on when you see this issue? I see you're doing USB passthrough, which can be a little be tricky. Can you reproduce the problem without USB passthrough? :-Dustin The specific USB device used is conditional on reproducing this bug. As such, I can't just reproduce this without the device. Right, sorry about that. I realized that just after I typed my response. My bad... :-Dustin This could fix it. commit c4c0e236beabb9de5ff472f77aeb811ec5484615 Author: Jim Paris
