[Bug 787091] Re: Unable to use USB device in KVM quest
@Daniele, I'm not sure what you are wanting to do. I suspect your best bet will be to go to askubuntu.com with details. I'm quite certain that this bug has been fixed for some time in libvirt, perhaps with http://www.redhat.com/archives/libvir- list/2010-November/msg6.html. I'm marking this Fix released. If anyone can reproduce this in raring please do re-open with detailed reproduction steps. ** Changed in: libvirt (Ubuntu) Status: Triaged => Fix Released -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to libvirt in Ubuntu. https://bugs.launchpad.net/bugs/787091 Title: Unable to use USB device in KVM quest To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/787091/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Serge, Thanks again for your assistance with this. I will leave cgroup un-mounted for now as I do not believe I lose anything by doing so.

[Bug 787091] Re: Unable to use USB device in KVM quest
I can only think of one other explanation, the devices cgroup. Can you, while that VM is running, do ps -ef to get the PID of the kvm process, then do cat /proc/$PID/cgroup (substituting in the pid)? Assuming it reads something like 1:blkio,net_cls,freezer,devices,memory,cpuacct,cpu,ns,cpuset:/libvirt/qemu/lxc-natty-amd64 you would then find the cgroups mountpoint using mount | grep cgroup and print out the device whitelist using: cat /cgroup/libvirt/qemu/lxc-natty-amd64 (substituting your cgroup mountpoint for '/cgroup'). If I'm not being clear enough here, please start by just giving me the output of: for p in `pidof kvm`; do cat /proc/$p/cgroup done mount | grep cgroup -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/787091 Title: Unable to use USB device in KVM quest To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/787091/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 787091] Re: Unable to use USB device in KVM quest
Please download this file and extract it using tar zxf openeperm_kprobe.tar.gz Then you'll need to install a few prerequisites: apt-get install make gcc linux-headers-2.6.32-32-generic Enter the extracted directory and compile the kprobe: cd openeperm_kprobe make This will compile a kprobe (kernel probe) which, while installed, will give more information on the credentials of any process which receives -EPERM or -EACCES trying to open a file. So the way to use it is, load the module, start the virtual machine which tries to use the printer, unload the module once it has failed (i.e. you see the messages about failing to open /sys/bus/usb/001/004), then unload the module and look through the logs for any meaningful information. Load the module using: insmod openeperm.ko Unload it using: rmmod openeperm You can see the error messages using the command 'dmesg', and they will look like: [ 148.939971] sys_open returned: -13 [ 148.939982] Call by: euid 1000 cap_eff 0 ** Attachment added: "openeperm_kprobe.tar.gz" https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/787091/+attachment/2185306/+files/openeperm_kprobe.tar.gz -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/787091 Title: Unable to use USB device in KVM quest To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/787091/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Re: [Bug 787091] Re: Unable to use USB device in KVM quest
Serge,
See below. The open program opens it and gets file ID 3 as one
would expect. Whilst running this the VM is outputting the not permitted
message on the same device. So root can open but libvirt cannot!

[Bug 787091] Re: Unable to use USB device in KVM quest
Let's see if we can get root in general to fail to open this. First
paste the following into 'open.c' (without the '' lines), and
then compile that using 'make open'.
===
#include
#include
#include
#include
#include
int main(int argc, char *argv[])
{
int ret;
if (argc < 2)
{
printf("try %s /dev/bus/usb/001/013\n", argv[0]);
exit(1);
}
ret = open(argv[1], O_RDWR|O_NONBLOCK);
printf("open returned %d\n", ret);
close(ret);
}
===
Plug in the printer and try starting the VM with libvirt. Look in the
log file to get the pathname it is trying to use. Then run open with
that file as argument. For instance if you see
/dev/bus/usb/001/004: Operation not permitted
then try
sudo ./open /dev/bus/usb/001/004
If it says it returned a positive number, then it succeeded in opening
it. If it returned -1, then we know that in fact root can't open that
device, and it isn't just libvirt.

[Bug 787091] Re: Unable to use USB device in KVM quest
Further to my previous comment, I have tried another printer which appears to install and work OK. Main difference I suspect is that this is an older printer and possibly USB 1.1 whereas the first printer I tries may possible only be USB 2.0. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/787091 Title: Unable to use USB device in KVM quest To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/787091/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Re: [Bug 787091] Re: Unable to use USB device in KVM quest
Serge, I would add that the system runs on software raid with LVM2 and it would seem that simply taking a full backup and restoring after trying alternative Kernel. is also non-trivial.

Re: [Bug 787091] Re: Unable to use USB device in KVM quest
Serge, Unfortunately I have only one vm capable host which is my main machine, firewall, PBS, family desktop etc. It is an AMD Phenom II, the only other kit I have is not 64bit and has no virtualisation capabilities.

[Bug 787091] Re: Unable to use USB device in KVM quest
Since KVM is running as root and the device is owned by root (and ACL gives 'user:rw' perms), I don't think the ACLs are to blame. Could you try booting the system with 'apparmor=0' in the boot arguments? If it works then, then we know apparmor is somehow still causing this. --- Ubuntu Bug Squad volunteer triager http://wiki.ubuntu.com/BugSquad -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/787091 Title: Unable to use USB device in KVM quest To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+bug/787091/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

Serge, My wrap is similar to the one you had suggested. I use virt-manager which lacks some capability in particular i wanted to pass multiple core to guests. The wrap makes no odds though as I have the same result when I do nots use it.

strace and writing to /tmp.

I can't reproduce this on my natty host which also has cups and the system-config-printer-gnome running. I don't have high hopes that they are in fact the culprit, but still it seems worth checking. Could you try removing system-config-printer-* packages and stop cups, sudo stop cups sudo apt-get remove system-config-printer-gnome system \ system-config-printer-common \ system-config-printer-udev Log out and back in, and see if after that kvm is able to use the printer. Then reinstall with apt-get install system-config-printer-gnome \ system-config-printer-common \ system-config-printer-udev sudo start cups when you are done. ** Changed in: qemu-kvm (Ubuntu) Status: New => Incomplete ** Changed in: qemu-kvm (Ubuntu) Importance: Undecided => Medium -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/787091 Title: Unable to use USB device in KVM quest -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs

[Bug 787091] Re: Unable to use USB device in KVM quest
Thanks for taking the time to submit this bug and helping to make Ubuntu better. dmesg has no more apparmor errors, so it is not likely the cause of the permission denial. But libvirt is supposed to change the ownership of the usb device so that libvirt can access it. So I'm not sure what is causing this. Could you append your /etc/libvirt/qemu.conf file, and /var/log/libvirt/qemu/VM.log where VM is the name of the libvirt vm and the result of 'ls -l /dev/bus/usb/001/004'. ** Changed in: qemu-kvm (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu-kvm in Ubuntu. https://bugs.launchpad.net/bugs/787091 Title: Unable to use USB device in KVM quest -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
