I've been using virt-manager and kvm with a disk image (as in the raw bits) from a physical windows 7 machine. Initial performance was dreadful, but improved as I switched to virtio and spice. I've been running linux VM's somewhat longer (much longer if you count kvm without libvirt). There are lots of choices exposed by virt-manager. How do I find out what the choices mean, and

Dear Boyland, In collaboration with some of this mailing list users, I had put some effort in optimising the guest settings in function of a windows guest. The libvirt-gui doesn't include these options. You'll have to edit the XML in virsh. This was my conclusion on 15-03-2015 but I added the hugepages tip in this list today. As for networking, I only use or bridged or the default virtual

Yeah, Dominique, your wiki was one of the many docs I read through before/during/after starting down this primrose path... thanks for writing it. I'm an Arch user, and I couldn't find anything to indicate qemu, as its compiled for Arch, will look in /etc/default/qemu-kvm. And now that I've got the right page size, the instances are starting... The reason I want to use the page element

As I mentioned, I got the instances to launch... but they're only taking HugePages from "Node 0", when I believe my setup should pull from both nodes.

Regarding fine tuning my explanation about what system does de actual mounting of Hugepages, you?re probably right?. Thanks for the correction. On upstart systems (like Ubuntu) the mounting of Hugepages is done by the init script qemu-kvm.conf Van: G.

Thanks Dominique & Daniel. Looks like i need to upgrade my VMs kernel to make it aware of virtio. Found this information from this link: http://wiki.libvirt.org/page/Virtio#Disk_.28block.29_device_driver I tried without upgrading the Kernel and as soon as i start my VM it got into Kernel Panic. I will try using virtio after upgrading my VMs kernel. Thanks for all the responses and

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

Hi there! I will do soon the disk config, but first I will do some labs. I´m trying to install the virtio driver to comunicate using qemu-agent but when the driver is installed, the BSOD happens (win2k8 R2). I tried with virtio-drivers version 100, 110 and 117, both happens BSOD. Do you has a tip ? :) Thanks buddy! 2016-05-20 10:23 GMT-03:00 Dominique Ramaekers <

Hi Dominique, You’ll have to convert the qcow to raw, create a LVM-volume (don’t create a file system on the volume), and dd the raw tot he LVM volume… Convert the qcow to raw, Ok Create a LVM-Volume, OK Don´t create a file system on the volume ?? Is not clear why... DD the raw to the LVM? How ? I don´t understand this point.... Thanks a lot! 2016-05-20 10:23 GMT-03:00 Dominique

Hi, I've got two hosts. Most of my guests are Windows systems. I'm using LANBench to test network performance. 1) From an physical PC to a guest (it doesn't matter on which host), I get almost 1Gb/s. They are connected through a 1Gb/s swich => very good! 2) From a guest on one host to a guest on the other host => plusminus 1Gb/s => Okay! 3) Between two guests on the same

Spice seems to be doing the trick... Thanks a lot! The tablet isn't removed or changed yet. I'll first do a follow up of the spice before doing that...

Hello All, I'm trying to enable hugepages, I've turned off THP (Transparent Huge Pages), and enabled hugepages in memoryBacking, and set my 2MB hugepages count via sysctl. I'm getting "libvirtd[5788]: Failed to autostart VM 'atlas': internal error: Unable to find any usable hugetlbfs mount for 16777216 KiB" where atlas is one of my guests and 16777216 KiB is the

Yes, my modification is like you. I doubt that if the mount operation on the host is reasonable… And what is p9?

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

Hi, I have tried usb and it doesn’t work. I don’t know if the filesystem tag could work… I find in the formatdomain docs about the filesystem: <filesystem type='mount' accessmode='passthrough'> <driver type='path' wrpolicy='immediate'/> <source dir='/export/to/guest'/> <target

I have been using libvirt for a while now with some linux guest installed. And everything has been working great. I've got a nice new (used) HP virtual host with 12 x dual core and 48Gb mem. My Windows servers are getting old, so I found it was time to take the next step and also virtualise my Windows systems. Now I've got two Windows guests on my new host: - A Windows 8.1 which runs a
