Hi Oleksandr,

Hi Masami

[sorry for the possible format issue]

 

I would like to try this on my arm64 board.

Glad to hear you are interested in this topic. 

 

According to your comments in the patch, I made this config file.
# cat debian.conf
name = "debian"
type = "pvh"
vcpus = 8
memory = 512
kernel = "/opt/agl/vmlinuz-5.9.0-1-arm64"
ramdisk = "/opt/agl/initrd.img-5.9.0-1-arm64"
cmdline= "console=hvc0 earlyprintk=xen root=/dev/xvda1 rw"
disk = [ '/opt/agl/debian.qcow2,qcow2,hda' ]
vif = [ 'mac=00:16:3E:74:3d:76,bridge=xenbr0' ]
virtio = 1
vdisk = [ 'backend=Dom0, disks=ro:/dev/sda1' ]

And tried to boot a DomU, but I got below error.

# xl create -c debian.conf
Parsing config from debian.conf
libxl: error: libxl_create.c:1863:domcreate_attach_devices: Domain
1:unable to add virtio_disk devices

libxl: error: libxl_domain.c:1063:domain_destroy_cb: Domain

Could you tell me how can I test it?

I assume it is due to the lack of the virtio-disk backend (which I haven't shared yet as I focused on the IOREQ/DM support on Arm in the first place).

Could you wait a little bit, I am going to share it soon.
