Re: GPT ERROR when write preempt img to sata on NUC7i5BNB


Liu, Fuzhong
 

Hi Siming

Please share your launch script and  run “lsblk” in sos console to check if sda is available.

Hi Fuzhong,

Thanks for the test.

I have update the Service VM with  Acrn Hypervisor 2.0 release and Acrn Kernel 2.0 release

# uname -a

Linux nuc-acrn 5.4.43-PKT-200203T060100Z #3 SMP PREEMPT Tue Aug 4 10:24:36 CST 2020 x86_64 GNU/Linux

 # acrn-dm -v

There is a new socket error,  does any help?

Hi Siming

Narrow down your issue here:  

As mentioned in below doc; please modify the script to use the virtio device.

https://projectacrn.github.io/1.6/getting-started/rt_industry.html#install-and-launch-the-preempt-rt-vm

5 Modify the script to use the virtio device.

# NVME pass-through

#echo ${passthru_vpid["nvme"]} > /sys/bus/pci/drivers/pci-stub/new_id

#echo ${passthru_bdf["nvme"]} > /sys/bus/pci/devices/${passthru_bdf["nvme"]}/driver/unbind

#echo ${passthru_bdf["nvme"]} > /sys/bus/pci/drivers/pci-stub/bind

/usr/bin/acrn-dm -A -m $mem_size -s 0:0,hostbridge \

   --lapic_pt \

   --rtvm \

   --virtio_poll 1000000 \

   -U 495ae2e5-2603-4d64-af76-d4bc5a8ec0e5 \

   -s 2,virtio-blk,/dev/sda \

   -s 3,virtio-console,@stdio:stdio_port \

   $pm_channel $pm_by_vuart \

   --ovmf /usr/share/acrn/bios/OVMF.fd \

   hard_rtvm

 

}

 

The reason about below error log for virtio-blk on your side is: your run sata passthrough script before; just reboot can fix it

>>>         acrn-dm: Could not open backing file: /dev/sdaListening 35...
>>> 
>>>         : No such file or directory

 

It is successful log on my side:

If you really want to passthrough SATA SSDto RTVM, please use acrn-kernel:
