Re: [Xen-users] xend http interface

Anand wrote:

Dear Anthony,

I looked at http://hg.codemonkey.ws/libxend, looks real nice. Is it complete ?

Just missing a few functions to access the VCPU information.. I have no plans to implement an interface to VNET.

I'm hoping it can be used as a backend for libvir. If you haven't checked libvir out, you should.

If i may ask what other work you are doing on xen ? I see xenfs there as well. I hope you won't mind sharing about your work.

Oh, I've got a fair bit of hg repositories there. xenfs is a FUSE filesystem that exposes a /proc like interface for Xen.

Anthony Liguori

And thanks for the pointer to XendClient.py.

    http://hg.codemonkey.ws/libxend

    Is pretty close to exhaustive except for scheduler operations and VNET
    operations.  Check out XendClient.py, that's the closest thing to
    a full
    list.
