[Qemu-devel] bind interdomain ioctl error xen-kvm.c

[Rishi Ranjan]

I am trying to use Xen as accelerator for my Qemu machine. I have created a
guest domain with following xl config:

builder = "hvm"
name = "qemu-hvm"
memory = "512"
vcpus = 1
vif = ['']
vnc = 1
boot="c"


When I try to run with following parameters:

-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:

"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,
                                 PROT_READ|PROT_WRITE, ioreq_pfn);

Can someone help me get this working?

Thanks,
Rishi
