Hi all, I''m not sure what qemu-dm does or how to debug its high CPU usage. Any one mind giving me a clue? - Brian _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Thanks Pasi, That explains it perfectly. I did a man qemu and found that it was an emulator but you supplied the needed tidbit, thanks. - Brian On Dec 1, 2009, at 2:07 PM, Pasi Kärkkäinen wrote:> On Tue, Dec 01, 2009 at 12:03:32PM -0800, Brian Krusic wrote: >> Hi all, >> >> I''m not sure what qemu-dm does or how to debug its high CPU usage. >> >> Any one mind giving me a clue? >> > > qemu-dm is the backend for (HVM) guest IO emulation. > > -- Pasi >_______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Xen virtualizes the CPU instead of emulating it; but for the rest of the hardware it borrows qemu code and runs under Dom0. the name qemu-dm stands for ''qemu device manager''. most (all?) open source virtualization solutions leverage qemu in similar ways. -- Javier _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
