Hi, I'm trying to passthrough legacy PCI ISDN controller to a KVM based virtual machine: <hostdev mode='subsystem' type='pci' managed='yes'> <source> <address domain='0x0000' bus='0x04' slot='0x00' function='0x0'/> </source> <address type='pci' domain='0x0000' bus='0x00'

Hi, libvirt (0.9.11) refuses to start KVM based virtual machines on my system when changing the network connection from "host bridge" to "direct" (macvtap/macvlan), neither in "bridge" nor in "vepa" mode: "Cannot create macvlan devices on this platform" That's astonishing because I can easily setup working macvlan devices using the

Hi, I'm running some Windows clients inside KVM virtual maschines managed by libvirt. These clients are managed by a Samba 3 PDC. Therefore the DHCP needs so supply corresponding WINS server (dhcp option 44) not only IP address and DNS server. Is it possible to make dnsmasq driven by libvirt to supply custom dhcp options? I would appreciate something like this in the network.xml: [...]

Hi all, Can anyone please advise the correct process for defining a USB device to point to a USB 2 Controller? Specifically, how do you define a USB device to use the EHCI controller in a guest xml file? To summarize my problem: I have 1 x USB1 device and 1 x USB2 device that I would like to use from within a Windows XP Guest. If I add the USB2 device (Avid M-box) to the guest machine via

I would really appreciate some pointers on what I am doing wrong here. I have a need to run multiple virtual guests which have each their own GPU and some USB controllers passed-through. I am able to run one of the guests like this (assuming vfio stuff has happened elsewhere), but I would prefer to use virsh: kvm -M q35 -m 8192 -cpu host,kvm=off \ -smp 4,sockets=1,cores=4,threads=1 \ -bios

I can see from different post that if working with sr-iov, i should work with vlan Is this an obligation to work with vlan if working with sr-iov? If not according to which parameter will the different vf get the traffic. Let's say i declare max_vfs=7, how will the traffic be seperated between the vm? However till i get an answer i tried to work with vlan And i still don't get

Hello! I'm trying to compile libvirt using GCC 5.1 but one of the test are failing and I have no idea why :( Hopefully someone of you could help me, here part of my log: ========================================== libvirt 1.2.14: tests/test-suite.log ========================================== # TOTAL: 109 # PASS: 107 # SKIP: 1 # XFAIL: 0 # FAIL: 1 # XPASS: 0 # ERROR: 0 .. contents::

Hi all, I'm using Samba (AD) under Debian Buster. Testparm tells me the idmap of TDB and AD would overlap. However the configured range don't.

Greetings all, I have a host machine that runs a router within a vm. I want to allow a connection between the host and the guest so the host can connect to the lan provided by the router vm. I've created a dummy interface with these commands: $ ip link add ens99-dummy type dummy $ ip link set ens99-dummy address 52:54:00:1f:d0:ff this resulted with this output: $ ifconfig ens99-dummy

Greetings, I have two machines running the same distro, both running qemu 5.1.0, one runs libvirt 6.7.0, the other 6.8.0. I've decided to test the viability of passing through my sata cdrom into a vm, so I went to the libvirt docs, read a bit and added the following to a debian10 uefi vm running on libvirt 6.8.0: <controller type='scsi' index='0'

How does one do this? For example: # lspci | grep USB 00:1a.0 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #4 (rev 02) 00:1a.1 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #5 (rev 02) 00:1a.2 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #6 (rev 02) 00:1a.7 USB Controller: Intel Corporation 82801I (ICH9

Hello, I have been working sometime now on getting a HVM accepting a PCI card from the host. As was said in the VT-D wiki I bought an ASUS P5E VM DO motherboard (rel 0803) which has the VT-D option in the bios. I want to pass a Hauppauge PVR 500 card to a virtual machine running LinuxMCE. After first trying XEN 3.2.1 which did not enable the "VT-D virtualisation" bit in xm dmesg, i

Sorry for posting bad debug info.

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

Hi All, I found it very difficult to get Xen-3.1 up on a a machine with Intel''s ICH9 family of disk controllers :-(. Is the ICH9 support really there in xen-3.2 ? I tried but was not successful in booting even xen-3.2 from xen.org. Did anyone have a success? Or any help on what extra config options I need to pass while compiling a domain0 from xen sources? Thanks, -- Pradeep Singh

Hi, I want to create a virtual hci device on my virtual machine. I have seen that qemu has options supporting this https://qemu.weilnetz.de/doc/qemu-doc.html#Bluetooth_0028R_0029-options and https://qemu.weilnetz.de/doc/qemu-doc.html#pcsys_005fusb Is there any support for these options in libvirt? I was not able to find anything in documentation so I added the qemu command line xml as follows
