Red Hat Bugzilla – Bug 1278189
KVM guests installation really slow, uses 200% CPU.
Last modified: 2015-11-04 16:56:44 EST
Description of problem:
Installation of Fedora-Live-KDE-x86_64-23-10.iso under KVM very slow
and uses all available CPU.
Records show 34 minutes of full load after I accepted to proceed with install .
Version-Release number of selected component (if applicable):
Guest: KVM Spice Fedora-Live-KDE-x86_64-23-10.iso
Installation of Fedora-Server-DVD-x86_64-23_Alpha.iso on same host went very rapid.
This was nothing like that
For the third attempt I selected simple graphics, but don't think that made a difference.
Steps to Reproduce:
1. Install Fedora-Live-KDE-x86_64-23-10.iso under KVM
UI response very slow. CPUs pegged to max.
GUI should be responsive.
Install should complete very quickly (<10 minutes)
and not eat all resources available on Host.
This reminds me of the 'GTK rendering under spice' problem created by the gratuitous use of unneccessary flashy screen updates in the installer.
