Re: [Xen-devel] Virtualization project idea

[Dhananjay Goel <dhananjaygoel123@xxxxxxxxx>]

Hi James/Pasi,

I had a look at http://wiki.xensource.com/xenwiki/XenUSBPassthrough

But I'm not sure if it supports sharing USB devices across VMs (host and guest) i.e. if I plug in a flash drive then it would detect in both host and guest and I'd be able edit files from all VMs rather than mounting and unmounting everytime from 1 VM to other.

Please let me know your thoughts on it.

Thanks,
Dhananjay

Further to what Pasi said, I have partially ported the backend interface
and can hand you the code if you want. It's probable a bit stale vs the
current kernels and leaks memory under some circumstances but is
probably better than starting from scratch.
