PVUSB support
I am in need of a method to pass USB devices that require higher
performance than the current qemu usb passthru method. I have read
about using pvusb, but I am unable to find any method to use pvusb or
kernel support for that matter. What can I do short of waiting for Xen
4.2 to be released with a new version of qemu?

Re: PVUSB support [ In reply to ]
I suppose that is possible. I am also having another issue after
compiling the xen-4.1.1 source code. I sent the issue to the xen-users
mailing list, but I think this is probably a more suitable place for the
issue

I just downloaded Xen-4.1.1 from xen.org, compiled it, and installed it.
I then compiled kernel 3.0.0 and added the hypervisor and dom0 kernel in
a grub 2 entry. After booting, I executed "xl list," to confirm the
hypervisor was running. I was greeted with this message:

libxl: error: libxl.c:56:libxl_ctx_init Is xenstore daemon running?
failed to stat /var/run/xenstored.pid: No such file or directory
cannot init xl context

I poked around and found there is a folder within /var/run called
"xenstored" and I found there was no service called xenstored
in /etc/init.d. There are the services I found in init.d:

xencommons
xend
xendomains
xen-watchdog

After extracting the xen source here are the commands I used to compile:

make xen
make tools
make stubdom
make install-xen
make install-tools
make install-stubdom
