You are correct - it wasn't configured.
The problem is - I have the package (ncurses-devel) installed, but it is not
detected.
KVM's "./configure" scripts skips it.
But it works on my Fedora machine.
I have a big problem

This is the first release of block and network drivers for Linux guests
running on a kvm host. The drivers are intended for guest kernels
2.6.18-2.6.24. Newer kernels include the drivers; older kernels may not
work. kvm-61 or later is needed in the host.
Network throughput is around 1 Gbit/s

First, thank you very much for making the patch.

get good results.

Use LSB of the address passed through the msr to enable/disable
the clock. Setting it to 1 enables it, setting it to 0 disables it.
As the guest data structures are aligned anyway, this
won't be a problem, as this bit is free.
Guest is changed accordingly

It's not a bad idea. What we really need is for people to submit

This patch writes 0 (actually, what really matters is that the
LSB is cleared) to the system time msr before rebooting/shutting down
the machine.
Without it, we can have a random memory location being written

Hi greg,
When I remove only the kvm-intel module without removing the kvm module itself,
I get an error saying that a kobject is

I will be off-line (and sometimes off-piste) from March 8 through March
15. I may have sporadic Internet access.
Andrew, should kvm.git not play nicely with the rest of the children,
