[Qemu-devel] [PATCH 0/4] tests/vm: various trivial fixes

[Philippe Mathieu-Daudé]

Hi,

These are various fixes I added to have the VM tests working for me.

Regards,

Phil.

Philippe Mathieu-Daudé (4):
  tests/vm: Support proxy / corporate firewall
  tests/vm: Add a dependency to qemu-img
  tests/vm: Only use -cpu 'host' if KVM is available
  tests/vm: Add flex and bison to the vm image

[Qemu-devel] [PATCH 1/4] tests/vm: Support proxy / corporate firewall

[Philippe Mathieu-Daudé]

If ftp_proxy/http_proxy/https_proxy standard environment variables
are available, pass them to the vm images.

As per 06cc3551714:
This is required when building behind corporate proxy/firewall, but
also help when using local cache server (ie: apt/yum).

Reasonable, but do we want it for other apps and images? How about setting these
env vars to ssh commands?

I see 2 different network usages:

1/ how the guest connect to the outer world, this goes via the firewall.
Here the change only affects apt* based commands (via the apt.conf file).
Do we have other commands requiring network connectivity? If we have,
then yes, we should add the same env vars in the guest.
One case I think of is "git submodule init" calling "git clone".

2/ how the host connect to the guest (ex: SSH).
In this case we use the loopback interface, thus no need to change.

Yes, I think this case is what we are looking at here. But this patch is very
specific: it only affects one command in one VM, albeit we don't have many.
Doing this means we'll need to specially open code tests/vm/fedora,
tests/vm/debian, or any other images we introduce later, to be consistent with
ubuntu.i386. It is a poor way to do this, IMO.

What I mean is, can we do it more generically? Like setting the env var in guest
/etc/profile or change BaseVM._ssh_do() to inject env vars:

[Qemu-devel] [PATCH 2/4] tests/vm: Add a dependency to qemu-img

Before the first use, the VM image are resized with qemu-img.

Add a dependency to the qemu-img tool to fix:

Oh since we want to use the shell PATH and not a make variable, it could
be cleaner to rather use:

No, please don't do this. Let's keep on supporting vm tests from a clean source
tree. Similar to qemu_bin, this can be handled in basevm.py.

The ubuntu.i386 VM is the only one using the qemu-img tool in his
build_image() method implementation. Is it OK to add this check there?
The basevm.build_image() is only an abstract method.

Maybe you can add a BaseVM.qemu_img() method that looks up for available
qemu-img on the system or build dir.

[Qemu-devel] [PATCH 3/4] tests/vm: Only use -cpu 'host' if KVM is available

[Philippe Mathieu-Daudé]

If KVM is not available, then use the 'max' cpu.

This fixes:

  ERROR:root:Log:
  ERROR:root:qemu-system-x86_64: CPU model 'host' requires KVM
  Failed to prepare guest environment
  error: [Errno 104] Connection reset by peer
  source/qemu/tests/vm/Makefile.include:25: recipe for target 'tests/vm/ubuntu.i386.img' failed
  make: *** [tests/vm/ubuntu.i386.img] Error 2
