[Qemu-arm] How to set RTC for ARM guest OS

[Daniel Chang]

Guys,

 

I used ‘-m virt’ to imitate ARM guest OS on X86-64 ubuntu. But the system time is always reset to Jan 1 of 1970 after reboot.

I tried ‘-rtc clock=host’  and ‘-rtc base=yyyy-mm-dd’ but seems it doesn’t work.

 

Does anyone know how to support RTC on ARM guest?

 

Thanks

Daniel
