Hi, We have a VM with several USB devices attached. Everything works well, but sometimes, after a reboot of the host, some usb device get a different bus/device number and that prevent the reboot of the VM : ------- error: Failed to start domain xxx error: internal error: Did not find USB device 04b9:0300 bus:1 device:5 ------- I guess this is because we have multiple usb devices with the same

Hi, I have been receiving messages on a new DomU''s kern.log. I''ve done a lot of googling, but haven''t came up with anything very useful, at least not in a Xen context. I was wondering if anyone had any suggestions about what could be wrong. From everything I have read, there should be a stack trace included, but I am not seeing one. Thanks in advance, Ian. on

Hi Konrad, Today i tried linuses tree of today (last commit is 4c4d285ad5665bfbd983b95fde8d7a477d24a361). It boots dom0 fine, but it fails to start any domU with: "Error: Failed to query current memory allocation of dom0." With my previous 3.1.5 kernel everything is fine, nothing else changed in config in between. dmesg and xm dmesg attached -- Sander Dom0 shows: total

Hi Konrad I encountered a bug when trying to bring offline a cpu then online it again in HVM. As I''m not very familiar with HVM stuffs I cannot come up with a quick fix. The HVM DomU is configured with 4 vcpus. After booting into command prompt, I do following operations. # echo 0 > /sys/devices/system/cpu/cpu3/online # echo 1 > /sys/devices/system/cpu/cpu3/online With
