Hello,
I’m trying to setup a file sharing between two DomUs using the 9p protocol as described in https://xenbits.xen.org/docs/unstable/man/xl.cfg.5.html#Devices.
When I use the following configuration in the XL config file it works, but it shares a folder from the dom0:
p9 = ['tag=test,security_model=none,path=/var’]
But when I want to connect to another DomU using the following config it does not work:
p9 = ['backend=p9-back,tag=test,security_model=none,path=/var’]
On the backend side I have no log…
On the frontend I have this in dmesg:
xenbus_probe_frontend: Device with no driver: device/9pfs/0
then I modprobe 9pnet_xen and I have the following in dmesg:
9pnet: Installing 9P2000 support
Initialising Xen transport for 9pfs
9pfs 9pfs-0: 2 xenbus_dev_probe on device/9pfs/0
9pfs: probe of 9pfs-0 failed with error -2
Can anybody help me understand and fix this issue?
My understanding now is that there might be a problem with the transport between the DomUs, and probably on backend side but what exactly? Is there any module to load in the backend? A configuration? I think I read all Internet pages related to xen and P9FS.
Some info on my environment:
- Dom0 : Alpine Linux 3.15.4-lts in a VMware Fusion 12 virtual machine
- Xen 4.15.2
- DomU : Alpine Linux 3.15.4-virt
Thank you
