Re: [Qemu-discuss] A few bugs and updating QEMU

[Jake Thomas]

Ok, here's an update. I still have no idea how to get qemu to complie, and I 
would love to know the actual ./configure options you people use to compile it 
succesfully, but here's the good news:

In ArchBang I got a version of Qemu new enough to not have the ISOLINUX bug. So 
that did get fixed. And it is obtainable without compiling from source. I just 
did "sudo pacman -S qemu".


Also, this version no longer has the "-M ?" and "-cpu ?" bug.

And it does default to 64-bit on a 64-bit machine, though to QEMU's virtual 
CPU, not to the common kvm processor. I was just worried there for a little bit 
that it defaults to 32-bit on a 64-bit machine.

So it's looking good. It would just be nice to know how to compile it.

Cheers,
Jake

original message:

I have QEMU 0.14.0 installed, which is the most recent version I can get with 
"sudo apt-get install qemu". I have tried to compile the latest QEMU out of the 
git as well as compile the 
latest released tarball. I could not get either the tarball or the git to 
compile, not even with 
--disable-werror. QEMU gets hung up on the ISOLINUX bootloader, thus I cannot 
boot the ArchBang 
installer iso. This is a known bug. Also, "--cpu ?" doesn't give a list of 
supported cpus to emulate/kvmerize, but 
"--cpu ?d" does. Same story with "-M ?". "-M ?" doesn't work but "-M ?d" does.
This is also known. Also, when I boot the ArchBang 64-bit installer (via Grub), 
unless I specify 
--cpu kvm64 it does not work. I'm guessing it doesn't work because it goes into 
32-bit mode unless I tell it otherwise. I think that is a bug because the 
default cpu option on a 64-bit machine with 
VT-x enabled and kvm installed and running in Linux should be --cpu kvm64. Why 
should I have to tell it that? Due to these 3 bugs, I would like to update 
QEMU, but I can't do that because I 
can't get past make in my compiling efforts. How do you folks compile QEMU? 
What ./configure options do you all use? Help would be appreciated. Thanks for 
your time,
Jake
