similar to: hotplug is not supported

Hi Daniel, I noticed that the patch "Add support for hotplug/unplug of disk devices in LXC" you wrote had been merged into libvirt of version 1.0.2. But when I used this function, it report an error with details as following: ubuntu@lxc:~$ vir attach-device instance-0000002c disk.xml --config error: Failed to attach device from disk.xml error: Unable to create device

Hi, Gao Feng I've tried what you said, but still exists the problem: ubuntu@lxc:~$ vir attach-disk instance-0000002c /dev/dm-0 sdb error: Failed to attach disk error: Unable to create device /proc/10366/root/dev/sdb: Permission denied I think finding what it means by saying 'Unable to create device /proc/10366/root/dev/sdb: Permission denied' is the key. But anyway, thanks for

Hello guys: I am using libvirt 0.9.4 on a CentOS 6.3 server.The operation of attach device won't work.It states "error:Operation failed.Device hotplug is not supported." When issue attach device command, there's nothing happen in guest dmesg log. Anybody came across this problem? Any help will be appreciated!

Hello, First of all, happy new year! I am interested in the hot plugging facilities of libvirt, in particular in what qemu calls 'hot add' of network interface cards. (And also the reverse: hot unplugging/removing of NICs.) I think I am overlooking something, but so far the best I have been able to find is: http://libvirt.org/sources/virshcmdref/html/ and it is not entirely clear

Hi experts, When I hotplug nic into lxc, the nic in lxc seemed to be down status as following: 1224: vnet0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000 link/ether fa:16:3e:fc:e5:96 brd ff:ff:ff:ff:ff:ff It seems mechanism such as udev is needed here. But I found udev is not supported well in lxc. So how can I get a 'up' nic after hotplug into lxc ? Very
