[Xen-users] Using XEN as accelerator with QEMU gives bind interdomain ioctl error xen-kvm.c

[Rishi Ranjan <rishi.rranjan@xxxxxxxxx>]

I am trying to use XEN accelerator with QEMU. For running my VMs with KVM on AWS, I have using nested virtualization solutions but I am exploring XEN accelerator to run my VMs directly on AWS.Â

I tried one of the VMs that comes with QEMU with XEN as accelerator to test it out but I am getting some errors. I am new to using XEN so need some help to resolve the issue.Â

I have created a guest domain with following xl config:Â

builder = "hvm"

name = "qemu-hvm"

memory = "512"

vcpus = 1

vif = ['']

vnc = 1

boot="c"

When I try to run with following parameters:Â

-machine q35,accel=xen -cpu qemu64 -bios ./pc-bios/bios-256k.bin -xen-domid "Domain id of guest"

I am getting follwing error from xen-hvm.c:Â

"bind interdomain ioctl error" in xen_hvm_init while calling     state->shared_vmport_page =

      xc_map_foreign_range(xen_xc, xen_domid, XC_PAGE_SIZE,

                ÂPROT_READ|PROT_WRITE, ioreq_pfn);Â

Can someone help me get this working?Â

Thanks,

Rishi
