I have finally taken the time to install hurd, as a start with qemu and

Hurders for your good work! In connection to the install I have a few
questions.
Installing Hurd with mini.iso as show in README.txt:
qemu -m 512 -net nic,model=ne2k_pci -net user -hda hurd-install.qemu
-cdrom ~/SW/hurd-installer/mini.iso -boot d
Installation went well, apt and grub2 work perfectly, however extremely
slow, several hours for the installation. After the install I tried with
-m 256, same common problem: one of the two CPUs loaded 100%, the other
idle, almost all memory used and sloow.
I've addressed your questions I believe that I can help with - sorry I
can't help with them all.
Do you find a lot of disc activity? I did, but the work around is to
start QEMU with these options (assuming you're using the latest QEMU
from git):
qemu -drive
file=debian-hurd-03102010-qemu.img,index=0,media=disk,cache=unsafe -boot
c -enable-kvm -net nic,model=rtl8139 -net user
After that I found hurd works very fast.
- How to shut down Hurd in qemu properly? Just closing the qemu window
hurd complained on an unclean shutdown and had to check disks. The
solution I found so far is to shut down Hurd as root in the qemu window
before closing the window.
I used to have that, now I do this:
'shutdown -h now'
It will fail. So then do this:
'poweroff'
Then I found that there is no need to fsck discs upon reboot.
- qemu seems to grab the mouse when clicking on the window, making it
impossible to copy text from that window somewhere else. Is that
solvable?
No
- qemu-kvm is also available in addition to qemu. Would things be faster
with it, there seems to be some kernel modules added? Does my CPU, see
below, support virtualisation?
Thanks,
Svante Signell
