[gentoo-dev] app-emulation/qemu-user mask

[Doug Goldstein]

Just wanted to give everyone a heads up. app-emulation/qemu provides
all the functionality of app-emulation/qemu-user without all the
outstanding security bugs and issues the package has. For users using
a cross chroot, I encourage you to look at QEMU_USER_TARGETS. I
presently use an arm chroot with app-emulation/qemu. Should there
truly be a missing feature, open a bug and I'll fix it. The only item
I'm aware of that app-emulation/qemu does not have is the binfmt
initscript. But I plan on adding that to the unstable version shortly.

If there are no objections for 30 days, I'll send a treecleaner notice
in 30 days and remove it 30 days after that (60 days from now).

Hi!

For cross-chroots its needed to have static qemu-$arch user translators. May 
be you can introduce user-static use flag for them? Also it will be cool to 
have init script for kvm

USE=static is available for app-emulation/qemu. I'll get a chroot for
arm setup soon and test everything to make sure its working well.


With regards to the KVM init script, I'm uninterested in maintaining
it and it doesn't belong in the package as it is. There's a number of
submitted init scripts that are attempting to create "init scripts"
but really they're re-inventing libvirt and ganeti, but instead
poorly. Ones I know about are:

It doesnt allow to build dynamik qemu-system* and static user targets

Ghm.. Its some kind of overkill to install libvirt or gannety just for 1-2 vms

There is a kvm/qemu init script system in the qemu-init overlay
available in layman

layman -a qemu-init

emerge app-emulation/qemu-init-scripts

It can handle most kvm/qemu setups.

It is the combined work of 2 active gentoo devs "Diego Petteno" who
created the main gentoo tinderbox, and Brian Harring.

  And does not work "poorly" and in my opinion works much better, easier
than libvirt, which I never did get working before getting a copy of
Brian's init script.

That can be fixed. File a bug.

To follow this up. I've successfully installed and am using an arm
chroot on my amd64 box using app-emulation/qemu-1.2.2 not using
USE=static. But it required a little bit of effort (using ldd or
readelf to bring in the necessary libraries) so I'll introduce
USE=static-user and USE=static-softmmu, both of which will be enabled
by USE=static.

And once I have enough time I will reinstate it... beside the fact
qemu-user does NOT have security issues...

Again please do not mix qemu system emulation with qemu userspace
wrappers. They have different needs and requirements.

qemu-user-1.2.2 in portage.

I'll drop the mask as said before.

We can discuss on irc or here on what's the best strategy today anytime.
