I have a device I want a guest to see. I've configured the following: % cat /etc/libvirt/HotPlug/owon.xml <hostdev mode='subsystem' type='usb'> <source> <vendor id='0x5345'/> <product id='0x1234'/> </source> </hostdev> And then in udev: % cat /etc/udev/rules.d/90-owon.rules

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

configure uses clock_gettime to check whether -lrt is needed - and don''t check other functions. With glibc 2.17 clock_gettime is part of libc, so use timer_gettime instead, which is in -lrt in old and new versions of glibc.

Hi Richard thanks for the info. I took the strace approach and ran into this looping over and over again. Is it failing to get time? timer_gettime(0x8, {it_interval={0, 0}, it_value={0, 0}}) = 0 timer_settime(0x8, 0, {it_interval={0, 0}, it_value={0, 250000}}, NULL) = 0 timer_gettime(0x8, {it_interval={0, 0}, it_value={0, 204443}}) = 0 select(16, [0 6 9 13 15], [], [], {1, 0}) = 2 (in [6 13],

When virtio-blk device is resized from host (using block_resize from QEMU) emit KOBJ_CHANGE uevent to notify guest about such change. This allows user to have custom udev rules which would take whatever action if such event occurs. As a proof of concept I've created simple udev rule that automatically resize filesystem on virtio-blk device. ACTION=="change", KERNEL=="vd*",

I created a 1TB RAID1. So far it is just for testing, no important data on there. After a reboot, I tried to mount it again # mount /dev/mapper/vg00-btrfsvol0_0 /mnt/btrfs0 mount: wrong fs type, bad option, bad superblock on /dev/mapper/vg00-btrfsvol0_0, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or

Hi all, I changed a bad disk (automaticly disabled from software raid1 and system for I/O error) in one of our servers and now have problem with adding new one to system without reboot. Does anybody have an experience with this? Or is it possible? :) We're using hotswap AXX6DRV3G for 6 SATA disks from Intel connected directly to MB (S5520HC from Intel too). There is AHCI as driver (enabled in

Hi, I got this error when starting a domU on Centos 5.1 i386, Device 0 (vif) could not be connected. Hotplug scripts not working. Why is this happening ? I should restart the machine to see if this still happends after a fresh network bridge. But it's somehow a production server, I would like not to restart it, if possible. No domU is currently running. I could start domUs a week ago.

Hi I'm debugging why echo cancellation does not work in my app using the DUMP_ECHO_CANCEL_DATA flag. What format does the data I receive have, looks like 16bit integers just dumped but when plotting it in MATLAB I do not get a raw audio data signal I expected.

Can you see the USB device in the lxc? My answering assumes you cannot see the USB device in the container. If you can see it, please ignore my answer. According to my understanding, “hostdev mode='subsystem' “ is used with KVM only. We use this if we want to passthrough a device to a KVM virtual machine. After doing that, the host machine will lose control of the device. If container is

When you pass a device in the pci chain (after virsh nodedev-dettach'ing it from host) to the guest, how much is passed without being emulated/abstracted?
