Hello, I've setup a VM with default networking (NAT) and this works fine but hosts on my LAN can't get to the VM since it uses NAT. When I try to set network to use MacVTap with either default or bridged I get no networking for the VM. Any hints around this? I would like to have the VM's on the same LAN as my host and other machines. I don't care if the VM host can't reach the

Hello, I have a simple C program that uses libguestfs to extract info about disk usage from a libvirt domain. It works when ran manually as root, but fails when started as a systemd service. I'm attaching the service file, source code and verbose logs from both the successful manual run and from the service journal. SELinix is disabled. Error messages: libguestfs:

Hi all, I got a new laptop recently and what worked before no longer works (Fedora 23 on the laptops in both cases)... I'm trying to get nested virtualization to work because I use the VMs on the laptop to simulate an HA cluster that itself hosts VMs. I don't care much at all about the performance of the nested VM, it's just there so that I can work on the cluster's code.

Hi Dominik, Sure, I beleive you can improve using: <cpu mode='host-passthrough'> </cpu> add io='native' <driver name='qemu' type='qcow2' cache='none' io='native'/> After that, please try again, but I can see other thing, for example, change the hda=IDE to virtio.

After saving a particular VM running WinXP, any attempt to resume it (even when no other VM's are running) generates the following error: olympus ~ # virsh restore /var/lib/libvirt/qemu/save/WinXP.save error: Failed to restore domain from /var/lib/libvirt/qemu/save/WinXP.save error: internal error: Failed to reserve port 5908 This started sometimes towards the end of last year with only the

Hi, I have a fedora27 system with a win10 guest trying to use photoshop 2015. I've adjusted the vram parameter for the guest to 512M with QXL, but photoshop still reports "3D features and some filters require 512MB vRAM and photoshop has detected less than that on your system." What is the proper way to adjust the vram value to provide at least 512MB vram? I've included my xml

Hi there! Although the guest has 2GB memory, the windows guest was adjusted to support this. I guess that the LVM is the best choice! I will save all images to other disk and re-build the partition with LVM. Do you recomend to use ext4 or zfs ? - About the apparmor, I have my doubts, I will try to disable and see what will happen! - About the tablet input device, I removed! Some forums say that

Using: edk2.git-0-20150803.b1141.ga0973dc.x86_64 edk2.git-ovmf-x64-0-20150802.b1139.gb234418.noarch On Fedora 22. Provisioning a i440FX system in virt-manager and attempting to boot results in successful EFI initialization, but the VM exits ungracefully after the bootloader (with F22 and CentOS 7 installer images). There's no really useful information in any of the logs. Using qemu-kvm

Hi, I have a fedora25 system with a Windows10 host and would like to use it for photoshop. However, it complains the video memory is too low. I'm using the QXL driver and it appears to be limited to 256MB? I've installed the Red Hat QXL driver in Windows. I have 4GB of memory allocated overall, and could allocate more if necessary. How do I increase the available video memory? Photoshop

Hi there! I have installed a new VM with Win2k8 and the serial virtio driver works fine. I don´t know why the other VM the BSOD happen! About the performance, I had the impression that only one core is used.....PID 8301 is a linux VM with 4 VCPU and 2 GB of RAM... ​ 2016-05-25 3:39 GMT-03:00 Dominique Ramaekers < dominique.ramaekers@cometal.be>: > > > *Van:* Thiago

Hello, I have first a question (and then may be a problem), that I have difficulties to understand and eventually to investigate. On each of my guests VM, I see constantly a RX dropped number increasing , Even if the VM does nothing ! ifconfig eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.100.15 netmask 255.255.255.0 broadcast 192.168.100.255

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 \ -bios
