Virt-install options, are important?

[klabacita]

Hi.

Centos.

I had read the manpage for virt-install, we can be very specific on each hvm we create, but is important?

My doubt is:

virt-install -n win8-1 -r 2048 -f /opt/win8/win8-disk.img -b eth0 --vnc --vnclisten=192.168.50.2 -v -c /opt/win8/win8.iso

and

virt-install -n win8-2 -r 2048 --hvm --vcpus=2 --cpuset=2-3 --disk path=/opt/win8-2/win8-disk.img --os-type=windows --os-variant=win2k8 -b bridge0 --noautoconsole --vnc --vnclisten=192.168.50.107 -v --cdrom /dev/dvdrw

Once installed and start working, does this settings affect in how my vm performance? or they don’t affect?

Thanks!!!
