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. It is also possible to bypass setup of rootfs if QB_ROOTFS is set to "none".

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. 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.

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.

2016-09-09runqemu: fix run from testimage with non-standard DEPLOY_DIR_IMAGEJoshua Lock1
testimage.bbclass uses runqemu to execute runtime tests on a qemu target, this means that bitbake is already running and `bitbake -e` can't be called to obtain bitbake variables. runqemu tries to work around being unable to read values for bitbake variables by inferring the MACHINE from the DEPLOY_DIR_IMAGE setting, however if a user sets that variable in a manner which doesn't follow the systems expectations (i.e. if running `bitbake -c testimage` against a directory of pre-generated images in a user-specified path) the inferring of the MACHINE name from the DEPLOY_DIR_IMAGE location will fail. It's possible that check_arg_machine() shouldn't cause runqemu to fail and that runqemu should proceed with the user-supplied value even if it can't be verified. This patch simply ensures that a workflow where the user sets DEPLOY_DIR_IMAGE continues to work without changing too much of the runqemu code.

Previously, runqemu had hard coded machine knowledge, which limited its usage, for example, qemu can boot genericx86, but runqemu can't, we need edit runqemu/runqemu-internal a lot if we want to boot genericx86. Now bsp conf files can set vars to make it can be boot by runqemu, and qemuboot.bbclass will save these info to DEPLOY_DIR_IMAGE/qemuboot.conf. Please see qemuboot.bbclass' comments on how to set the vars. * Re-write it in python3, which can reduce lines from 1239 to about 750 lines * All the machine knowledges are gone * All of the TUN_ARCH knowledge are gone * All the previous options are preserved, and there is a new way to run runqemu: (it doesn't need run "bitake -e" in such a case) $ runqemu tmp/deploy/images/qemux86 or: $ runqemu tmp/deploy/images/qemuarm/<image>.ext4 or: $ runqemu tmp/deploy/images/qemuarm/qemuboot.conf * Fixed audio support, not limited on x86 or x86_64 * Fix SLIRP mode, add help message, avoid mixing with tap * Fix NFS boot, it will extract <image>.tar.bz2 or tar.gz to DEPLOY_DIR_IMAGE/<image>-nfsroot when no NFS_DIR, and remove it after stop. * More bsps can be boot, such as genericx86 and genericx86-64. * The patch for qemuzynq, qemuzynqmp, qemumicroblaze has been sent to meta-xilinx' mailing list. * I can't find any qemush4 bsp or how to build it, so it is not considered atm.
