d18003726f runqemu: Add workaround for APIC hang on pre 4.15 kernels on qemux86
On pre 4.15 host kernels, an APIC window emulation bug can cause qemu
to hang. On 64 bit we can use the x2apic, for 32 bit, we just have to
disable the other timer sources and rely on kvm-clock.

fae2e2f42d runqemu: Allow the user to override the device tree option
Update the runqemu script to allow the user to specify a device tree
to boot when calling runqemu.

This involves creating a seperate check_dtb() function incase the user
has specified 'none' for the kernel but still wants a device tree.

3ee7dcf68b runqemu: Improve relative path handling in qemuconf files

1889fb3455 runqemu: Ensure we process all tap devices
The regexp in the script misses some tap devices, e.g. we see output like:

runqemu - INFO - Acquiring lockfile /tmp/qemu-tap-locks/tap25.lock failed: [Errno 11] Resource temporarily unavailable
runqemu - INFO - Acquiring lockfile /tmp/qemu-tap-locks/tap26.lock failed: [Errno 11] Resource temporarily unavailable
runqemu - INFO - Acquiring lockfile /tmp/qemu-tap-locks/tap27.lock failed: [Errno 11] Resource temporarily unavailable

runqemu - INFO - Acquiring lockfile /tmp/qemu-tap-locks/tap41.lock failed: [Errno 11] Resource temporarily unavailable

What happened to tap29 to tap39?

The issue is was we were missing devices with '0' in the number,
like "10:" and so on in the output from "ip link".

9d07c736e3 image: Convert vmdk/vdi/qcow2 to strict CONVERSION_CMD types
The vmdk/vdi/qcow2 IMAGE_FSTYPEs predate wic.  As such, they provide
some similar underlying functionality in order to produce a "disk" image
that in turn can be converted into different formats that various
hypervisor types work with.  They do not however provide the ability for
other disk image types to be converted into these same output types.
Furthermore, they are less flexible than what wic does provide.  This
drops the old style vmdk/vdi/qcow2 types and re-introduces them under
the CONVERSION_CMD framework.  The equivalent of vmdk is now wic.vmdk
and so forth for the other types.

96a87592d4 runqemu: reworked exception handling
Introduced custom RunQemuException that script raises on known
errors. This exception is handled in one place and prints
error output without printing Python traceback. This shoud make
error output less scary for the end user.

Handling of unknown errors has not been changed - both error and
traceback will be printed.

Reimplemented OEPathError exception code to handle it similarly
to RunQemuException.

Moved exception handling code into main() to keep it in one place.

44c0e8c804 runqemu: change terminal settings for valid tty's
runqemu uses stty to change terminal settings to give users
better control to qemu. However, stty does not work when
runqemu is run directly or indirectly via oe-selftest in
a Docker container (presumably some problems with Docker's
pseudo-tty implementation).

The error reported is:
stty: 'standard input': Inappropriate ioctl for device

As runqemu recently moved to subprocess.check_call() for
stty calls we now get thrown an error and all runqemu
runs fail.

sys.stdin.isatty() does proper job in detecting if the stty
calls can work so we use that check before running the stty
subprocess operations.

2e09dc1be7 scripts: Fix return value checks from subprocess.call()'s
Python function subprocess.call() returns the return value of the
executed process. If return values are not checked, errors may
go unnoticed and bad things can happen.

Change all callers of subprocess.call() which do not check for
the return value to use subprocess.check_call() which raises
CalledProcessError if the subprocess returns with non-zero value.

https://docs.python.org/2/library/subprocess.html#using-the-subprocess-module

All users of the function were found with:

$ git grep "subprocess\.call" | \
  egrep -v 'if.*subprocess\.call|=\ +subprocess\.call|return.*subprocess\.call'

Tested similar patch on top of yocto jethro. Only compile tested
core-image-minimal on poky master branch.

68e57fa748 runqemu: independent network and rootfs setup
Presently, runqemu sets up rootfs as part of network setup.
In case there is no network desired we will end up without rootfs
as well.
This patch sets up network and rootfs independently.
It is also possible to bypass setup of rootfs if QB_ROOTFS is set to "none".

b4b2d6dec4 scripts/runqemu: avoid overridden user input for bootparams
Currently runqemu hardcodes the "ip=" kernel boot parameter
when configuring QEMU to use tap or slirp networking. This makes
the guest system to have a network interface pre-configured
by kernel and causes systemd to fail renaming the interface
to whatever pleases it:

  Feb 21 10:10:20 intel-corei7-64 systemd-udevd[201]: Error changing
      net interface name 'eth0' to 'enp0s3': Device or resource busy,

Always append user input for kernel boot params after the ones
added by the script. This way user input has priority over runqemu's
default params.

715f4e3ec1 runqemu: support UEFI with OVMF firmware
In the simplest case, "runqemu qemux86 <some-image> qcow2 ovmf" for an
EFI-enabled image in the qcow2 format will locate the ovmf.qcow2
firmware file deployed by the ovmf recipe in the image deploy
directory, override the graphics hardware with "-vga std" because that
is all that OVMF supports, and boot with UEFI enabled.

ovmf is not built by default. Either do it explicitly ("bitbake ovmf")
or make it a part of the normal build
("MACHINE_ESSENTIAL_EXTRA_RDEPENDS_append = ' ovmf'").

The firmware file is activated as a flash drive instead of using the
qemu BIOS parameters, because that is the recommended method
(https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=764918#47) as it
allows storing UEFI variables in the file.

Instead of just "ovmf", a full path to an existing file can also be
used, just as with the rootfs. That may be useful when making a
permanent copy of the virtual machine data files.

It is possible to specify "ovmf*" parameters more than once, then
each parameter creates a separate flash drive. This way it is possible
to use separate flash drives for firmware code and variables:
$ runqemu qemux86 <some-image> qcow2 ovmf.code ovmf.vars"

Note that rebuilding ovmf will overwrite the ovmf.vars.qcow2 file in
the image deploy directory. So when the goal is to update the firmware
while keeping variables, make a copy of the variable file and use
that:
$ mkdir my-machine
$ cp tmp/deploy/images/qemux86/ovmf.vars.qcow2 my-machine/
$ runqemu qemux86 <some-image> qcow2 ovmf.code my-machine/ovmf.vars.qcow2

When Secure Boot was enabled in ovmf, one can pick that instead of
the non-Secure-Boot enabled ovmf.code:
$ runqemu qemux86 <some-image> qcow2 ovmf.secboot.code my-machine/ovmf.vars.qcow2

63f61a1aff runqemu: also accept -image suffix for rootfs parameter
The magic detection of the rootfs parameter only worked for image
recipes which embedd the "image" string in the middle, as in
"core-image-minimal".

Sometimes it is more natural to call an image "something-image". To
get such an image detected by runqemu, "-image" at the end of a
parameter must also cause that parameter to be treated as the rootfs
parameter.

Inside the image directory, "something-image" has an -<arch> suffix
and thus no change is needed for those usages of
re.search('-image-'). However, while at it also enhance those string
searches a bit (no need for re; any()+map() a bit closer to the
intended logic).

8b448ab012 runqemu: allow bypassing of network setup
At present it is silently assumed all QEMU machines support networking.
As a consequence, one cannot run QEMUs without network emulation
using "runqemu".
This patch allows bypassing any network setup providing the qemuboot.conf
file contains:

When invoking "runqemu" with a mistyped image or architecture name,
the resulting error message is about the missing qemuboot.conf,
without any indication about the root cause:

Including the name of the actual file the scripts expects to find plus

 Exception: Failed to find <image>.qemuboot.conf = .../tmp-glibc/deploy/images/intel-corei7-64/core-image-mimimal-intel-corei7-64.qemuboot.conf (wrong image name or BSP does not support running under qemu?).

The comment about the BSP is included because that would be the real
reason why the file might be missing.

9dd223bf18 runqemu: fixes for slirp, network device and hostfwd
Fixed:
- Add QB_NETWORK_DEVICE to set network device, it will be used by both
  slirp and tap.
- Set QB_NETWORK_DEVICE to "-device virtio-net-pci" in qemuboot.bbclass
  but runqemu will default to "-device e1000" when QB_NETWORK_DEVICE is
  not set, this is because oe-core's qemu targets support
  virtio-net-pci, but the one outside of oe-core may not,
  "-device e1000" is more common.
- Set hostfwd by default: 2222 -> 22, 2323 -> 23, and it will choose a
  usable port when the one like 222 is being used. This can avoid
  conflicts when multilib slirp qemus are running. We can forward more
  ports by default if needed, and bsp.conf can custom it.
- Use different mac sections for slirp and tap to fix conflicts when
  running both of them on the same host.

5ea3627dbb runqemu: support multiple qemus running when nfs
Fixed:
* In build1:
  $ runqemu nfs qemux86-64
  In build2:
  $ runqemu nfs qemux86-64

  It would fail before since the port numerbs and conf files are
  conflicted, now make runqemu-export-rootfs work together with runqemu to
  fix the problem.

* And we don't need export PSEUDO_LOCALSTATEDIR in runqemu, the
  runqemu-export-rootfs can handle it well based on NFS_EXPORT_DIR.

* Remove "async" option from unfsd to fix warning in syslog:
  Warning: unknown exports option `async' ignored

* Fixed typos

Both slirp and tap can work.
