Is this still the case? If yes, I would like to take a look and would you
please to show me what I should test with GNU Mach as it looks like somebody is
already booting it on top of KVM.

Thanks,

Well, yes, of course, I didn't wait for KVM to fix this bug and let
people think that GNU Mach just does not work while it's actually KVM
which has a bug... Right after submitting the bug I've made GNU Mach
enable CR0_NE. The simplest way to test is probably to checkout
revision 8d4fdfbe43628119fc87920239704fe3d240d8a2 of
git://git.sv.gnu.org/hurd/gnumach.git and try to boot it e.g. using
grub's multiboot command.

I followed the notes to install netinst.iso
(http://people.debian.org/~sthibault/hurd-i386/installer/cdimage/netinst.iso)
on KVM but the guest OS hangs at "Select and install software" -- "Running
post-installation trigger install-info"
Is it a known issue?
sudo /usr/local/kvm/bin/qemu-system-x86_64 -m 1024 -net nic,model=rtl8139 -net
user -hda hurd-install.qemu -cdrom netinst.iso -boot d -vnc :4 -no-kvm-irqchip

No, it is not a known issue. Which task(s) did you install?
Note that you do not need to install GNU/Hurd to build GNU Mach, just
git clone git.savannah.gnu.org:/srv/git/hurd/gnumach.git
and autoreconf -i && ./configure && make. If you have a 64bit box, you need to
cross-compile:
CPP='gcc -m32 -E -x c -undef -ansi' CC='gcc -m32' LD='ld -melf_i386'
./configure --host=i686-unknown-linux-gnu
Thinking again about, IIRC the kernel will just boot fine, it's only in some
application use case that the issue shows up. I'll attach a patch which shows
the CR0 value before and after Mach changes it. The 0x20 flag currently shows
up both before and after. It should only show up after (because Mach sets it).
To easily get the boot logs, pass console=com0 as kernel parameter during the
multiboot command, that will direct logs to the serial port.
