question - installation speed F11 Beta VM on F11 Beta physical
by mike.hinz＠yr20.com
Hi,
I have an F11 Beta server, fully updated to the latest and greatest from rawhide. I've noticed that whenever I try to install F11 beta in a VM, it installs really, really slowly, may 2 orders of magnitude slower than on the phyical machine. The physical server is a single processor quad-core Xeon with 8GB of RAM. I've set the VM to have 4GB RAM w/2 cpus.
It appears that the installation seems to be occcuring from the network versus the DVD. Why would this be and how can I speed up this incredibly slow process?
Thanks in advance for any help on this!

Mark,
I just wanted to follow up on this thread. Do you have any clue as to what
is going on with the very slow install?
It appears to me that my config is correct. Any light you can shed on
this issue would be most appreciated.
Thanks.

how to get rid of a hung VM install?
by Robert P. J. Day
as a test to warm up for a virt seminar i still plan on giving, i
tried to install f11 x86_64 inside of f11 x86_64. i got as far as the
graphical fedora screen, at which point the install hung. and now, i
can't get rid of that VM.
since i figure i pooched the install anyway (probably should have
selected the basic video driver), i'm trying to simply delete any
traces of that VM, but i can't. the VMM "Edit"'s dropdown menu has
the "Delete Virtual Machine" selection greyed out. no matter what i
do, when i restart the VMM, there's my "f1164" VM, no matter how hard
i try to get rid of it.
so what are my options?

p.s. i did the above with no loaded HW extension modules, just to see
the effect. not sure if that makes a difference.

qemu user emulation test package, and is GUEST_BASE broken?
by Robert P. J. Day
moving on, i'm continuing to document QEMU on f11 here:
http://www.crashcourse.ca/wiki/index.php/QEMU_on_Fedora_11
and i have (unsurprisingly) a couple of questions.
when i first started playing with QEMU a while back, i found the
user emulation test tarball here:
http://www.nongnu.org/qemu/linux-user-test-0.3.tar.gz
really handy to see what worked and what didn't. is there any chance
of bundling up something like that and turning it into another fedora
QEMU package? maybe "qemu-user-tests" or something like that, if
there are no licensing restrictions? i think a number of beginners
would find that useful. (the test script in that tarball,
"qemu-linux-user.sh", could be simplified tremendously, of course.)
and, more technically, the following attempt to test user emulation
for ARM (and ARMEB) using that test tarball fails thusly (running as a
non-root user):
$ qemu-arm -L gnemul/qemu-arm arm/ls
mmap: Permission denied.
$
apparently, this is because ARM tries to mmap to *very* low memory,
and the /proc/sys/vm/mmap_min_addr file is, by default, set to 65536.
the alleged solution is explained here:
http://archive.netbsd.se/?ml=qemu-devel&a=2008-04&t=7231855
to set the environment variable GUEST_BASE to 65536. now, that might
have worked once upon a time, but it doesn't seem to work now. on the
other hand, if you have root access, you can just:
# echo 0 > /proc/sys/vm/mmap_min_addr
and things suddenly work just fine. should GUEST_BASE work? or is
one reduced to needing root access to change that setting on a global
basis? and once i know the answer, i'll add it to my wiki page. cuz
that's just the kind of guy i am. :-)

The first problem is you need to call g.wait_ready() after g.launch ()
and before running any other commands.
The guestfs(3) manual page is informative on this subject.

Looks like a missing dependency. I'll push something to
git in a moment.

We'd greatly prefer an auto-generated interface, which is how
guestfish, the Perl bindings and the OCaml bindings, and all the
documentation are done. (And is also much easier to do and maintain).

Seems like you need ocaml-findlib-devel (for the OCaml bindings). See:

clarifying the fedoraproject wiki "qemu/kvm" features page
by Robert P. J. Day
i'd like to clarify a couple things here, if i might:
https://fedoraproject.org/wiki/Features/KVM_and_QEMU_merge
first, given that that page refers to being 100% done WRT f11,
should it represent *exactly* what i see on my current f11 beta
system? as in, no outstanding issues?
next, under "Detailed Description", point 5:
"The kvm package is obsoleted by qemu-kvm."
can i assume that "qemu-kvm" is a typo as there appears to be no such
package? what *should* that say? perhaps "qemu-kvm-tools?"
i have a few more questions about the merging of qemu and kvm but
i'm going to have to think about those for a few more minutes.
