Multiseat in Qemu
Posted: Wed 12 Nov 2014, 13:08
I managed to get a multiseat (2) solution with qemu using 2 monitors and 2 input ( kb + mouse) sets.
One can use the parameters with Qemu Control Centre provided by mikeb or qemu-vm-manager provided by jamesbond in Fatdog or use directly the terminal .
I used this code from the console:
qemu-system-x86_64 -enable-kvm -vga vmware -m 2048 -smp cores=2 -usbdevice hostc52b -soundhw ac97 -cdrom *.iso
Using kvm helps a lot (speed up) .
I'm using vmware video because installing vmware driver on the guest OS gives the best result for playing videos . Here , qemu is still slower than Virtual Box , so I want to look for a way to pass through the host video card to adress this issue too .
For keyboard and mouse I pass through the host usb device identified by vendor_id:product_id :
-usbdevice host:vendor_id:product_id
Vendor_id and product_id I got typing lsusb in the terminal.
About sound : for the guest , one can choose the emulated sound card that works
better , in my case -soundhw ac97 is just fine . I noticed that if qemu starts when the host system is using one specific sound card , that card is assigned to qemu .
Then I switch to the second card ( the one provided by my AMD card through HDMI - in my case ) and both host and guest have separate audio.
