Since several months I have performance problems with my Windows 10 virtual machine.
The host system (Intel Core i5 750, 2.8 GHz; 16 GB RAM; 3 TB WD Red harddisk for the VMs) with openSUSE TW (Qemu 4.0) should be strong enough to run a single Windows 10 desktop in a virtual machine. Other VMs (Linux, FreeBSD) are running without performance problems.
But if I start Windows 10 as a single Qemu KVM guest system, the desktop of the host system sometimes becomes unresponsive during Windows boot. The performance of the Windows 10 desktop is bad, approximately 10-20x slower than native and the host system performance also becomes worse.
I had the performance problems with Windows 10 1809. Now I installed a fresh Windows 10 1903 machine. The performance is better compared to the old VM, but also bad.
I implemented the common performance hints: - enough hard disk (55 GB) and RAM (2-5 GB) and CPU cores (2) for the guest system - all available Virtio drivers (disk, network, balloon, spice, tablet) installed - disabled disk cache (currently cache='unsafe', but also tried cache='none') - HyperV options enabled (see https://bugs.launchpad.net/qemu/+bug/1775702)
Here is my Windows 10 1903 quest setup: http://paste.opensuse.org/view/56376915
Does anyone has a working configuration on TW or configuration hints for me?
I also wonder about the following "CLOSE WONTFIX" comment on https://bugzilla.redhat.com/show_bug.cgi?id=1690641 "For me this is fixed in the EV variant of the software."
Qemu-ev is Redhat's own version of Qemu?
Greetings, Björn Hi I'm using UEFI, pc-q35-4.0, RH virtio for the disk and gpu passthrough.
Two cores (i5-3470S) and 4G RAM allocated. I'm using this setup for openSUSE/SLE and Windows guests. The only thing I did on the WinX (1903v1) guest was remove unused apps (xbox, game bar, onedrive etc), however also killed of SearchUI.exe (aka Cortana) as that was a hog, now I have a reasonable WinX desktop for testing. I don't see any lagging on the host (Tumbleweed) or guests... The next thing I see is TiWorker.exe busy... updates.... -- Cheers Malcolm °¿° SUSE Knowledge Partner (Linux Counter #276890) Tumbleweed 20190708 | GNOME Shell 3.32.2 | 5.1.16-1-default Intel DQ77MK MB | i5-3470S X4 @ 3.60 GHz | Intel Ivybridge HD 2500 up 3:25, 2 users, load average: 7.98, 3.07, 1.37 -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
