My host is a Gentoo with a 3.2.14 vanilla kernel, and I'm using the qemu-kvm package, which is the qemu found on http://www.linux-kvm.org/ . I run a few VMs on it, so yes KVM is enabled in my kernel and being used. Just to make sure, I started qemu with the -no-kvm option (since it's actually enabled by default) and it took GRUB about 1m30s to start. So the problem is really specific to the disk I/O. > > How can I improve the overall performance level of the system to make it > > usable? > > As Svante mentioned, enabling the writeback option should help. Indeed, I used these options and now the system is really usable, thank you Svante. I'd like to point out that this problem occurs only with Hurd, whenever the next version is available I'll try again with the default cache. > > As a bonus, is it possible to increase the default size of the > > console? 80x25 feels a bit cramped. > > Loading a 8x8 font should work to get 50 lines.

I was looking for something a bit more user-friendly here :) I'll use ssh then, I set up some custom system with a bridge on the host for the network connections, so I don't have to bother redirecting ports, hurd gets its own private address :) > Samuel Thank you both again for your help! -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
