I'd also like to point out that, when setting up a linux container with _just_ the lxc tools available in ubuntu, all that was needed to be done was whitelist the appropriate cgroups for the Android devices. The lxc tools seem to create the appropriate character devices when you detach/attach the Android device via USB, and the Android `adb` tool recognized the devices. So, a tangential

So, if I remove the hostdev element related to the USB device, running `lsusb` and `usb-devices` inside the container lists the proper device, but I do not see the appropriate character device bus for the Android device under /dev/bus/usb. We are not entirely sure that `lsusb` and `usb-devices` queries the appropriate location - it somehow gets information from the host, not the guest container,

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

Ah, nevermind, think my last post may not have been entirely correct. We've spent some more time correlating the log output from our failed LXC startup via libvirt [1] with libvirt code from the 1.2.2 tag. Interestingly, the error we get back is different, and digging through the multitudes of logs, nothing comes up about 'operating not permitted' regarding the USB bus that I saw

Hi, how can I define passthrough of all USB-slots to a guest with libvirt? With qemu it's very easy: # kvm -usb -usbdevice host:0.* -usbdevice host:1.* -usbdevice host:2.* -usbdevice host:3.* ... This configuration of the VM gets *all* 4 USB-Slots. Every time somewhat USB-device is plugged in the VM gets it. virt-install manpage offers: --host-device 001.003 USB by bus, device

Me again! Think we've found it. By diving into the LXC logs for the specific container, we found this: 2014-04-17 21:07:06.066+0000: 2861: debug : virCgroupSetValueStr:678 : Set value '/sys/fs/cgroup/devices/machine/oshi32134.libvirt-lxc/devices.allow' to 'c 189:130 rw' Looks like libvirt the permission to 'rw', not 'rmw' [1], so no surprise that when it

To follow up on this a little bit, tail'ing kern.log while trying to get our little container up doesn't yield anything with apparmor complaining, so, unless I'm looking in the wrong spots for apparmor logs (which I don't think so, as I see other apparmor-related log entries in kern.log), I am not entirely sure this is an apparmor issue at this point.

Dear Fil, I am not sure if my answer can help you. I had ever asked a similar question to Daniel and I was using a thirty-party card. As a container uses a shared kernel with the host, so hostdev mode='subsystem' doesn't make sense. Maybe you can try to use hostdev mode='capabilities'. Please see http://libvirt.org/formatdomain.html#elementsHostDevCaps Hope this helps Cheng

Yeah, AppArmor is enabled, but I put everything (that I could find) into complain mode: $ sudo apparmor_status apparmor module is loaded. 12 profiles are loaded. 3 profiles are in enforce mode. lxc-container-default lxc-container-default-with-mounting lxc-container-default-with-nesting 9 profiles are in complain mode. /sbin/dhclient /usr/bin/lxc-start

Further followups! We are correlating DEBUG-level output from libvirt with the libvirt 1.2.2 code to try to figure out what libvirt is doing under the hood. Even though we have the log level set to 1 (info) in our libvirtd.conf, we are not seeing the VIR_DEBUG() [1] statements being printed out. There are tons of other presumably-debug lines of output showing up in our log. We are sort of

So I am reading through , and am wondering what is the difference between <hostdev mode='subsystem' type='pci' managed='yes'> <hostdev> and <interface type='hostdev' managed='yes'> </interface> if I am trying to give full access to a NIC? Which one exposes more of the card? On Wed, Apr 24, 2019 at 1:13 PM Mauricio Tavares

Hello, I have been struggling as of late to successfully configure a pci passthrough using libvirt with kvm. Hoping someone can shed some light on the problem. Overall my experience with virtualization limited is so please forgive. The guest runs fine till passthrough is configured. I am using virt-manager. This has been tried on both a Fedora17 x86_64 and Arch Linux x86_64 build with pretty much

Thank you for your reply, I'm still getting hard time to attach the hostdev, I couldn't make it work out of the doc. I took the address details from: # ll /sys/bus/scsi/devices/7:* lrwxrwxrwx 1 root root 0 Feb 8 12:58 /sys/bus/scsi/devices/7:0:0:0 -> ../../../devices/pci0000:00/0000:00:03.0/0000:08:00.1/host7/rport-7:0-0/target7:0:0/7:0:0:0 lrwxrwxrwx 1 root root 0 Feb 8 12:58
