o2ib module prevents shutdown
Hello,
Not sure if this is the right forum: I''m encountering difficulties
with o2ib which prevents an LNET shutdown from proceeding:

Re: [virt-tools-list] Linux host / Windows guest sharing
Thank you. The clipboard sharing working now. Do you have any idea for
the mount issue? I suppose there is a way to share a specific directory
between the guest and host like I did with vbox for example
What exact modules needed for this function?
The error message I've got this:
mount -t 9p -o trans=virtio,version=9p2000.L hostshare /tmp/hostfiles
mount: special device hostshare does not

Re: [virt-tools-list] Linux host / Windows guest sharing
Thank you. It is clear now, so it was user error and I should read more
documentation :)
Unfortunately drag and drop isn't working. Is there any prerequisite?
My host is FC20 and guest is Win2k8 server
Thank you
Vlad

Re: LXC + USB passthrough = Operation not permitted
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

Re: [openib-general] problems with lustre o2ib module & ofed
It seems that lustre puts its modules in /lib/modules/2.6.16.21-0.8-default
despite the fact that my kernel is 2.6.16.21-0.8-smp !

Re: If it's possible for a third-party PCIe card to be shared by multiple containers
Dear Daniel,
I found that lxc driver doesn't support hostdev with type of 'pci'.
As you mentioned before, I tried to expose the device node (the PCIe card) to the container, my XML is as follow:
<devices>
<hostdev mode='subsystem' type='pci' managed='yes'>
<source>
<address bus='0x01' slot='0x00'

Re: LXC + USB passthrough = Operation not permitted
Hi Chang Weng,
Thanks for answering!
Could you explain why subsystem=USB does not make sense? I was simply
following the documentation for USB devices (right above the section you
linked to).
For what it's worth, I've also tried mounting the specific character device
related to the appropriate android device into the container in the way you
suggest, with no luck; `adb` still does not

RDMA Volume Mount Not Functioning for Debian 3.4.beta4
Anyone ele having these issues mounting RDMA only volumes under Ubuntu? Install of Gluster via: https://launchpad.net/~semiosis/+archive/ubuntu-glusterfs-3.4
I'm guessing this build is looking for an include somewhere that is just misplaced?

Re: LXC + USB passthrough = Operation not permitted
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,

Re: LXC + USB passthrough = Operation not permitted
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
