similar to: libvirt attaching wrong usb device?

hi,all a qemu-kvm process and its disk(image file) have the same MCS(s0:c111,c555). it express this process have access to this image. i do not know the power to access its image file is the max or min? if any other power this process(domain) has?how much? i want to know the exact power a qemu-kvm process has besides access its image file ,other kinds of files,dirs etc. my test case:

Yesterday I cloned one of my VMs and, somewhat implausibly, it took virt-clone something like 8-9 hours to clone the 8Gb disk image... Copying it from the command line took a mere 6.5 minutes. I assume this is a bug, and it's not expected to take this long ;-) This was using virt-clone from python-virtinst-0.500.2-1.fc12.noarch in the virt-preview repository. Tom -- Tom Hughes (tom at

Hi all, I've disabled cgroups v1 on my system with the kernel boot option "systemd.unified_cgroup_hierarchy=1". Since doing so, USB hotplugging fails to work, seemingly due to a permissions problem with BPF. Please note that the technique I'm going to describe worked just fine for hotplugging USB devices to running domains until this change. Attaching / detaching USB devices

I have a SCSI tape backup unit attached to a kvm host managed by libvirt. Is there a way to expose the SCSI device in libvirt so I could pass the device to a virtual machine and have the virtual machine control the tape backup? Defining the device as a SCSI disk does not appear to work. In this situation, live migration is not an issue. The VM would always be tied to this host.

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

Hi, I'm trying to attach a host FC HBA to VM (NPIV). Running ovirt 3.5 on CentOS 6.7, libvirt-0.10.2-46.el6_6.6.x86_64, I created vHBA using nodedev-create command - see below HBA and vHBA. I wrote a vdsm hook which appends the vHBA xml stanza to the devices xml element but the vm start starts without the vHBA device. Also, when trying to attach the device manually as a live device - I get:

is anybody else having problems with the new java 1.6.0.22 ? i am tried both cortado-ovt-debug and cortado-ovtk-debug - neither seem to work anymore once i installed the new java. once i go back to the old java 21 everything works fine. my jar file downloads for console messages (below) came from: http://downloads.xiph.org/releases/cortado/cortado-ovtk-debug-0.6.0.jar i have included

Hi ! During linking LLD and other linkers builds a static hash table for dynamic symbols, so that in runtime dynamic linker can use this table and find symbols faster. --hash-style=style linker option is used to select the hash type: "Set the type of linker's hash table(s). style can be either "sysv" for classic ELF ".hash" section, "gnu" for new style GNU

I’ve tried that post .. but either I get a new scsi passthrough controller in device manager, but no dvd or the boot in windows hangs Either that method won’t work anymore or my config is bad .. im not really sure what to put in controller, target, bus and unit ..

This patch exposes a generic interface which can be expanded in the future to implement USB for PVUSB, qemu, and stubdoms. It can also be extended to include other types of USB other than host USB (for example, tablets, mice, or keyboards). For each device removed or added, one of two protocols is available: * PVUSB * qemu (DEVICEMODEL) The caller can additionally specify "AUTO", in

Is the only way to attach a usb device to a vm first specifying the device, <hostdev mode='subsystem' type='usb' managed='no'> <source> <vendor id='0x3080'/> <product id='0x1234'/> </source> </hostdev> and then booting the vm while the device is attached? Can't I

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

When you pass a device in the pci chain (after virsh nodedev-dettach'ing it from host) to the guest, how much is passed without being emulated/abstracted?

Right now all the users experienced this problem seems to be using the i3 window manager, I don't know if this is reproducible with windowmaker. I don't know the mesa version they use, I will ask. But judging that they are
