2017-04-28runqemu: support virtio drive typePatrick Ohly1
Setting QB_DRIVE_TYPE=/dev/vd selects virtio without triggering any warnings. Previously, that was only possible by setting an unknown value and relying on the fallback to virtio, which caused some warnings to be printed.

2017-03-21runqemu: output network configurationEd Bartosh1
runqemu adds network configuration parameters to the kernel command line to configure guest networking. This works only for the images that run with external kernel using qemu -kernel parameter. It doesn't work for the images that use bootloader to boot kernel as -kernel parameter is not used and network configuration is not possible to get. Added host and guest ip addresses and netmask of tap link to the runqemu output. This should allow external programs that execute runqemu to get network configuration.

2017-03-16runqemu: independent network and rootfs setupJuro Bystricky1
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.

2017-03-04scripts/runqemu: avoid overridden user input for bootparamsDmitry Rozhkov1
Currently runqemu hardcodes the "ip=" kernel boot parameter when configuring QEMU to use tap or slirp networking.

2017-02-28runqemu: support UEFI with OVMF firmwarePatrick Ohly1
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 Signed-off-by: Patrick Ohly <patrick.ohly@intel.com>
2017-02-28runqemu: also accept -image suffix for rootfs parameterPatrick Ohly1
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). Signed-off-by: Patrick Ohly <patrick.ohly@intel.com>

2017-01-23runqemu: fixes for slirp, network device and hostfwdRobert Yang1
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.
