They can be resolved like this:
1) Edit /etc/libvirt/qemu.conf, and add "/dev/net/tun" to the
cgroup_device_acl option
2) Run: setcap cap_net_admin+eip /bin/qemu-system-x86_64
This will give QEMU CAP_NET_ADMIN when it runs. Make sure you review
`man capabilities` to see what capabilities this actually gets qemu.
The downside here is that in the event a guest somehow breaks out of
qemu, CAP_NET_ADMIN giv...

USB-hotplugging fails with "failed to load cgroup BPF prog: Operation not permitted" on cgroups v2
...c/util/virbpf.c#L54>
but I have no clue what that syscall is doing, so that's where my
debugging capability basically ends.
Maybe this is something as simple as setting the right ACL somewhere. I
haven't touched /etc/libvirt/qemu.conf except for setting nvram. There
*is* something about cgroup_device_acl there but afaict that's for
cgroups v1, when there was still a device cgroup controller. Any help
would be greatly appreciated.
Domain log files:
Upon execution of the above commands, nothing gets added to the domain
log in /var/log/qemu/wenger.log, so I've decided they're likely

Problem passing qemu cmdline option when using <qemu:commandline> in domain xml.
【Sorry there I maked some mistake in my first email, here is the correct one.】
I am trying to pass-through the parallel port of the host to the guest.
When I just used qemu-system-x86_64 with option '-chardev parallel,id=charparallel0,path=/dev/parport0 -device isa-parallel,chardev=charparallel0,id=parallel0', it worked perfect.
But when I tried to pass these option by adding lines below

Re: vhost-net requested but could not be initialized
Currently in the VM XML, I am passing the following command line argument
as a passthrough argument:
-netdev type=tap,id=net1,script=no,downscript=no,ifname=port3,vhost=on
-device
virtio-net-pci,netdev=net1,mac=00:00:00:00:00:01,csum=off,gso=off,guest_tso4=off,guest_tso6=off,guest_ecn=off
Is there another way to represent this in the XML file? maybe that may
solve the problem.

Bridging Wireless Cards for KVM
Hi,
I hope this is the right place to ask this question. I was wondering if
there is a way to set up a KVM VM using an XML document as input into Virsh
that uses bridged networking over a wireless card.
I understand that wireless cards to not natively support, but I was able to
find a working solution here:
http://blog.ericwhite.ca/articles/2011/04/creating-a-wireless-bridge/.
The issue is, I
