Greetings, I have the following machine: https://dpaste.com/5BPA3F77F which I'm trying to boot in uefi. /etc/libvirt/qemu.conf looks like this: https://dpaste.com/B3SFHUY6R and the ovmf files exists in the path, see: # ll /usr/share/edk2-ovmf/OVMF_CODE.fd /usr/share/edk2-ovmf/OVMF_VARS.fd /usr/share/edk2-ovmf/OVMF_CODE.secboot.fd /usr/share/edk2-ovmf/OVMF_VARS.secboot.fd -rw-r--r-- 1 root

Greetings, up until a year ago, I was running a server with Debian 10 (stable) on it with the latest versions of libvirt, qemu and kernel 4.19.x Debian 10 had to offer (both libvirt and qemu versions were really old). the network config was simple, one of the vm acted as a router and provided the ip for both the host and the vm. I've recently switched distro and now I'm running latest

Greetings, I have a vm on debian 9.5 to which I pass an specific usb from the host. here is the relevant part in the vm's xml file: <hostdev mode='subsystem' type='usb' managed='yes'> <source> <vendor id='0x148f'/> <product id='0x5572'/> </source> <address type='usb'

Greetings, I have a server that run a vm with several nic pcie cards as pass-though. the board has an intel gpu and the hdmi output is not used. I thought of booting up another vm and pass the gpu into it. I found several discussions on the subject stating that it isn't possible but all of them are several years old. I wonder if that has changed? is there a way to pt the vga to a vm? Thanks,

Greetings, I've setup an vm with openwrt in it, defined a isolated lan between the vm and the host and booted the vm up. I see the vm is up, made sure the vnic is visible in both the host and guest and added it to the br in the guest. I've issued an dhcpd call on the vnic (labeled vnic0) in the host and got an ip, see: dagg@NCC-5001D ~ $ dhcpcd vnet0 DUID

Greetings, I have a qemu line which I want to convert ot libvirt xml but as domxml-from-native is deprecated, I want to try it the other way around. e.g. write an libvirt xml and dump the final qemu line without running it. is there a way to do so? Thanks, Dagg.

Greetings, I need to get a device like this: https://www.pulse-eight.com/p/104/usb-hdmi-cec-adapter I have usb pass-through experiences with some usb devices such as dtv, wireless network, thumbsticks and wireless keyboards.

Greetings, I was wondering what is the proper way to configure a scsi cdrom pass-through so in when the qemu line is generated, host_Cdrom will be used instead of host_device. looking at https://gitlab.com/libvirt/libvirt/-/blob/master/src/qemu/qemu_block.c#L1090, I see that hostcdrom must be true. in order for that to be true, the following must be (see
