virtual guest instance. The CentOS-6.2 virtual host has a
4-port serial card installed.

USB-hotplugging fails with "failed to load cgroup BPF prog: Operation not permitted" on cgroups v2
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.

Emulated TPM doesn't work on Debian Buster
Hi. I am very interested in the security properties a totally open TPM
can give our users? - its use as a universal smartcard to protect all
types of keys. When adding the virtual 1.2 or 2.0 TPM I get the vague
error below. OS is Debian stable with standard packages.

libvirt/KVM/virt-manager to do any kind of DHCP. I'm currently using xml
