I am trying to build xen hypervisor for imx8mqevk target by command "bitbake xen-image-minimal" but its failing at do_rootfs.

Hello Vipul,

The error says it can't find a package named repo. Was such a package generated? For this error I strongly recommend to erase and reinstall the yocto again. Or maybe you are playing with non-supported ubuntu version.

Hi,

Thanks for reply!

I am building xen hypervisor for imx8mq target. Does xen support imx8mq ?

If support is available how i can find device tree source for the same, xen supporting dts files are available for imx8qm & imx8qxp only.

kernel: 4.19.35

u-boot: 2019.04

host: ubuntu 16.04

Looking forward for your response.

Thanks & Regards,

Hello,

Xen is not supported in MX8MQ, still working on it,  but it will be supported in at least two more BSP.

Hi,

Any suggestion on the supporting hypervisor. Is there any timeline specified for Xen support on imx8mq?

Would like to hear from you.

Thanks & Regards,

Hi,

Thanks for reply!

I am trying to load yocto based linux OS in each core of imx8mq EVK. OS in each core should be isolated. Can you suggest which hypervisor can serve my purpose?

I tried jailhouse but looks like it only support RTOS in non-root cells & as you mention Xen doesn't support imx8mq. Looking forward to hear from you on this.  

Thanks & Regards,
