The guest system is Windows XP Pro i386 and the USB device is a Panasonic PBX KX-TES824, identified by lsusb as "04da:1683 Panasonic (Matsushita)". The USB is used to set up and configure the phone switching system, it is supposed to be normally idle. After a few days connected, the USB stops to respond within the guest system. Need to physically unplug the device and plug it back to recover, once the condition is triggered. I have made no farther diagnostics, it was easer to use a dump workaround: since the USB link is used few times in a year, I do a "xm usb-add" before I use it and a "xm usb-del" once I finished. Never needed to touch it again. I have not monitored the memory consumption, son I can''t tell if this is about the same memory leak you report. Greetings. -- Alexandre Kouznetsov
