crosvm/kernel repository overview
curl -X POST https://cloud.docker.com/api/build/v1/source/ecb07fb7-6c0a-4dea-a319-63af05318824/trigger/5411b383-107e-4e7b-9934-ad12d19301b6/call/
reference kernel image for running on crosvm
a quick demo:
docker export $(docker create crosvm/kernel) | tar xvf - --strip 1 payload
docker export $(docker create crosvm/crosvm) | tar xvf - --strip 1 payload
env LD_LIBRARY_PATH=$PWD ./crosvm run vmlinux.bin
the kernel does boot but shortly panics with error messages as shown below:
...
[ 0.938342] VFS: Cannot open root device "(null)" or unknown-block(0,0): error -6
[ 0.939733] Please append a correct "root=" boot option; here are the available partitions:
[ 0.941253] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
...
(click here for full log)
it's normal because the kernel can't find a rootfs to continue booting with
rootfs
For the sake of completeness, you may want to attach a rootfs to the kernel, which is out of the scope of this short document. Please take a look at crosvm/rootfs for more info
