HI, everyone: My target deal with network hotplug use virDomainDetachDeviceFlags. Because when the API return ,the network maybe doesn’t remove from my vm guest os. So I use virConnectDomainEventRegisterAny to register an event ID: VIR_DOMAIN_EVENT_ID_DEVICE_REMOVED , my process as follow:

Hi, According to the docs on http://libvirt.org/html/libvirt-libvirt.html#virDomainDetachDeviceFlags I ought to be able to do virDomainDetachDeviceFlags( <domain>, <devicexml>, VIR_DOMAIN_DEVICE_MODIFY_LIVE | VIR_DOMAIN_DEVICE_MODIFY_CONFIG); to detach a volume both from a currently running VM instance and permanently from the defined config file. If I actually try that,

Hi All, I find that I am able to attach a disk device do a Xen domain, using virDomainAttachDevice(), running as a non-root user, but I am unable to use virDomainDetachDevice() - it results in an "unknown failure". Using "virsh [attach|detach]-device" exhibits this behviour. $ virsh attach-device domu1 attach.xml Device attached successfully $ virsh detach-device domu1

hi, all I do a hotplug detach a network in a thread, because virDomainDetachDeviceFlags maybe asynchronous, so I do like follow: cb_para->cluster_id = info->cluster_id; cb_para->group_id = info->group_id; cb_para->vsys_id = info->vsysid; cb_para->vnf_id = info->vnf_id; cb_para->conn = conn; cb_para->time_out = 20*1000;//20s

Thank you for your help! 1, i used vda as install disk and vdb as target disk, because i boot from the first. After setup boot order flag i was able change install disk to vdb and target disk to vda. With this configuration when i boot from vdb i can install OS with grub and after it redefine XML without vdb without problem. Thanks a lot. 2, maybe i have something wrong, but still not working:

Hi all, I just watched the rail video: http://www.rubyonrails.org/media/video/rails_take2_with_sound.mov I am just curious. I can tell that the video was done on a Mac, but I cannot tell which applications were used for editing the code, and for interfacing with MySQL database. As far as editing source code, I normally use BBEdit (I''ve used it since 1994), but the editor used in

Hi! We're struggling to get device detaching to work reliably using Xen. We can reliably use the same code to manage devices using Libvirt+KVM without any problems. We've tested this on Xen with both CD-ROM and USB devices without success. See below for detailed descriptions. Thankful for any help! Regards, Daniel Espling --- For CD-ROM, we can mount them using attach-device but

Hi, one quick&dirty way of backing up a pool that is a mirror of two devices is to zpool attach a third one, wait for the resilvering to finish, then zpool detach it again. The third device then can be used as a poor man''s simple backup. Has anybody tried it yet with a striped mirror? What if the pool is composed out of two mirrors? Can I attach devices to both mirrors, let them

hi, all: I create a vm with six nic, after the vm start, i delete tree nics. all the three nic delete logic will happen in a thread , every nic delete has the following process: int vnf_control_del_network(void *arg) { 。。。。。 call_id = virConnectDomainEventRegisterAny(conn, dom, VIR_DOMAIN_EVENT_ID_DEVICE_REMOVED, VIR_DOMAIN_EVENT_CALLBACK(vnf_control_del_network_cb), cb_para,

Hi, I have the following happen to me after the restart of one of my servers: out of my 3 PRIs (all configured with the same technical settings), the last one isn't coming back. It's underutilized (chances it didn't get a call since my reboot), if it makes a difference . The PRI goes from provisioned to unprovisioned, and I get this regularly: [Jun 22 09:03:48]

Hello, I have some difficulties regarding to above title. Windows as guest OS is running on KVM(Ubuntu natty). After attaching LVM volume to guest OS and did "safely remove device" in guest windows, detaching volume was failed. > root at localhost:/opt/win# virsh detach-disk testwin vdc > error: Failed to detach disk > errpr: operation failed: detaching virtio-disk2 device

This puzzles me. If I start asterisk in the background, and then attach to it to perform some chores, is there a way to detach again without stopping the background process? Entering "stop now" kills both the console attachment as well as the background process. I need to attach to the running asterisk in order to do "init keys" but once I do that, it seems I cannot just

Is it possible to start asterisk in the foreground ("asterisk -fc") and later detach from the terminal but leave asterisk running? thanks, James

Devices with on-chip IOMMU may need to restore iotlb to 1:1 identity mapping from IOVA to PA. Before vhost-vdpa is going away, give them a chance to clean up and reset iotlb back to 1:1 identify mapping mode. This is done so that any vdpa bus driver may start with 1:1 identity mapping by default. Signed-off-by: Si-Wei Liu <si-wei.liu at oracle.com> --- drivers/vhost/vdpa.c | 17
