Hi Anthony and other Qemu/Xen guys,
We are trying to enable venus on Xen virtualization platform. And we would
like to use the backend memory with memory-backend-memfd,id=mem1,size=4G
options on QEMU, however, the QEMU will tell us the "-mem-path" is not
supported with Xen. I verified the same function on KVM.
qemu-system-i386: -mem-path not supported with Xen
So may I know whether Xen has any limitation that support
memory-backend-memfd in QEMU or just implementation is not done yet?
Looking forward to your reply!
Thanks a lot,
Ray
