runqemu: check the qemu PID has been set before kill()ing it

2021-12-14T22:49:22+00:00

If runqemu is killed, check that we have a valid PID for the qemu before sending a kill() to it.

runqemu: use "raw" instead of "bin" for ovmf

2021-03-18T21:20:25+00:00

bin is not an acceptable format for qemu and will throw an error is set. The correct format in this case is raw.

runqemu: Add a hook to allow it to renice

2020-09-17T11:51:24+00:00

We have an issue where qemu is being starved of resources on our autobuilders. We can't raise its priority without special capacilties, therefore add a hook which if present can allow this to happen using an executable "~/runqemu-renice".

runqemu: Show an error for conflicting graphics options

2020-09-02T15:04:37+00:00

The autobuilder managed to pass the nographic option with "sdl gl" due to a problem elsewhere. It would have been useful for runqemu to have errored rather than passing conflicting options to qemu. Add an error for this invalid usecase.

runqemu: Check gtk or sdl option is passed together with gl or gl-es options.

2020-08-27T07:25:50+00:00

runqemu help reports that gtk or sdl option is needed with gl or gl-es option. But if user forgot to add gtk or sdl option, then gl or gl-es options were silently skipped.

runqemu: add QB_ROOTFS_EXTRA_OPT parameter

2020-07-02T15:12:36+00:00

Content of the optional parameter will be appended to the rootfs-device in the qemu configuration, in case QB_ROOTFS_OPT is not specified. By default this is empty. Example use cases are: Defining 'readonly' when using squashfs, so multiple instances of qemu can share the same base image, something that cannot be done by just specifying 'snapshot'. Defining 'bootindex=0' which helps to get past the EFI shell in ovmf-binary. This also enables the use case of running WIC images with EFI bootloader through the testimage.bbclass.

runqemu: Change nfs to mount via TCP

2020-03-29T19:04:10+00:00

Since kernel commit b24ee6c64ca7 ("NFS: allow deprecation of NFS UDP protocol"), NFS UDP has been disabled by default due to the potential data corruption caused by fragmentation during high loads. So now we cannot boot up with nfs mode and default kernel. We'd better turn to use TCP accordingly.

runqemu: support multiple NICs

2020-03-21T22:39:00+00:00

Emulating more than one network interface with runqemu is a bit tricky, but possible. For example, the following leads to an emulated device with eth0 and eth1: QB_NETWORK_DEVICE_prepend = " \ -device virtio-net-device,mac=52:54:00:12:34:03 \ " or QB_NETWORK_DEVICE_append = " \ -device virtio-net-pci,mac=52:54:00:12:34:03 \ " When booting Qemu with two NICs, the kernel does not know which interface the specified ip=192.168.7.... command line argument should be applied. This delays the boot process for a very long time and a guest wihtout IP configuration. This add two new configuraton parameters to runqemu: QB_CMDLINE_IP_SLIRP and QB_CMDLINE_IP_TAP to explicitely specify the ip= kernel command line arguments for tap and slirp mode. Note: Simply adding "::eth0" broke some builds on the Yocto autobuilder. (From OE-Core rev: 59bfdc331c1494c05ab38804b281878a1f571f6d) Signed-off-by: Adrian Freihofer Signed-off-by: Richard Purdie

runqemu: Add network bridge support

2020-01-10T21:18:23+00:00

Qemu supports attaching the virtual machine to an existing network bridge interface via the qemu-bridge-helper program (as long as the system is correctly configured to give the user permissions). Add support for runqemu to do this also via the "bridge=" argument. Note that for this to work correctly, the host qemu-bridge-helper must be used, not the one that might have been built by qemu-native. In order for qemu to correctly find this program, a qemu-oe-bridge-helper program has been added to qemu-helper-native, and runqemu will use this helper as the bridge helper. The helper will look for the host qemu-bridge-helper first by looking in the QEMU_BRIDGE_HELPER environment variable, then by search common paths where the helper is installed.
