Hello Libvirt Community,
For the last 18(!) years, libvirt community mailing lists have been kindly
hosted by Red Hat Corporate IT on the redhat.com Mailman installation.
In retrospect this wasn't the ideal home for community mailing lists but
that decision is ancient history.

I'm not sure what you mean. Editing XML manually is different to using
libvirt APIs to detach hostdevs. Here's how it works:
1) a domain is defined (say using virsh define file.xml), libvirt parses
this XML, keeps it in a memory and stores it "somewhere"

Hello community,
I would like to know if there is an api to get a virtual machine's
uptime. Thank you in advance for the help.

have learned that although my temporary fallback Virtualbox allows
forwarding by vendor ID without a product ID

Hey folks,
I am curious to understand a bit more the core use of the emulatorpin CPUs

For example :
In this case :
- The VM has 4 vCPUs.
- Each of the core is pinned to a physical/thread core - 34,14,10,30
- The emulatorpin is also attached

the virtual machines from an external network but I can access them inside the
server. I would like to know what would be the best way since we want to have
a single public ip and be able to have a reverse proxy to access

Good morning I'm Eduardo, a computer science student and I'm doing a final
course work focused on virtualization. The work consists of creating virtual
machines on a server and allowing ssh access to the virtual machines that are
on the server containing qemu/kvm/libvirt. The problem is that I

Hello,
For one of our case validation, we were using direct QEMU commands before for
VM creation as it was easier to configure the VMs. Inside VM we do run the
real-time latency test.
Recently we switched to libvirt for the VM creation and deletion. Surprisingly,
we do see a significant

It's since libvirt-6.2.0 but IIUC you're running on unsupported CentOS 7
which doesn't have that release available.

Hi Daniel,
Thank you to Peter and you for the analysis – that was very helpful.
Indeed, it can happen that we restart the firewall during this scenario on our
system so I think I can debug from here.
By the way, you mentioned that there is a libvirt version where QEMU process
gets its own

Online I’ve read that you should run this command: `# gdb -batch -p $(pidof
libvirtd) -ex 't a a bt f'`. I’ve run that command and attached the output to
this mail. However, I have to admit that I have no idea what to do with it.
