For anyone who might have been following this thread, I accidentally forgot to add fedora-xen to the recipient list before sending my last reply. It is below, along with a response from Avi. I updated my F8 box, and sure enough, kvm-60 was installed. I thought I had just done that and kvm-55 was where it stopped, but I must be crazy or something. Also, I got the gplpv drivers by James Harper installed and functional as of version 0.9.2 (I had no luck with 0.9.0 or any prior version). That said, I probably won't go any further with my quest for kvm, at least not in the near future. The stdvga emulation kvm uses (or at least used on kvm-47) was nice with the standard vesa drivers referenced on the kvm site (went higher than 1024x768), and those drivers don't work for the stdvga=1 option in xen, but I think the potential performance gain from the multiple paravirtual drivers will be more important for me. Also, as I didn't follow up on it, I did try to install CentOS 5.1 on this machine and it does not support the network card, so I am on Fedora 8 as originally recommended by Emre. Dustin

It doesn't look like F8 is likely to get up to kvm-58 either.
F8 is up to kvm-60.
I prefer to stick with the Fedora repositories for the machine I am working with, as I don't want to run into compatibility issues on account of some future update. However, I want to try to use the network driver, as I am hopeful that it might make an apache application I am running perform better. It is also possible that I really need disk drivers for that. Would compiling a newer version of kvm on Fedora 8 be risky (in terms of interoperability problems after some future update)?
No.
Also, assuming the answer to that is no, do I need to remove any certain packages first to
make
sure they don't update and overwrite it?
No. Do a ./configure --prefix=/opt/kvm-69 and all files will be placed there.
Finally, on the Fedora repo versions of KVM for F7 and F8, I can't create a VM with 2 GiB of RAM. Was this a known kvm bug at some point (or worse, is it still?), or could it
be
a problem with Fedora (I can do this fine in xen)? Thanks,
For more than 2GB of RAM in a guest, you need a 64-bit hypervisor. Large guest support was added in kvm-47 (2TB guests were booted).
