PCI Passthrough
Hi,
I'm trying to passthrough legacy PCI ISDN controller to a KVM based
virtual machine:
<hostdev mode='subsystem' type='pci' managed='yes'>

<address domain='0x0000' bus='0x04' slot='0x00' function='0x0'/>
</source>

Cannot create macvlan devices on this platform
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

Passing dhcp-options
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:

Specifying a USB Device to use USB2 Controller
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

PCI passthrough fails in virsh: iommu group is not viable
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 \

Re: Sr-iov passthrough - no packet arrive to guest
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

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.
Thanks in advance,

connecting host and guest vm using a dummy nic
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

scsi passthrough differs between guests
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:

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

[Q]Are Intel''s ICH9 chipsets supported by xen-3.2?
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,

Bluetooth Device Support
Hi,
I want to create a virtual hci device on my virtual machine. I have seen
that qemu has options supporting this

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
