Hello. Can somebody tell me, if i use win-gpl-pv drivers, how can i
access xenstore?
I found one project in github with patch, but it apply cleanly only on
top of old revision of drivers. (containt gntmem and xenstore userspace
libs) (github.com/smowton/xen-pv-windows-evtchn) Can somebody forward
port it to newer version?
How can i write application, what read some info from xenstore under
windows?

And second question - does windows gpl-pv drivers contains some code to
emulate serial devices like in Linux (/dev/hvc0) ?

Thank You for all answers and helpful links.

The shutdownmon in gplpv uses xenstore to do its thing. The interface isn't well tested beyond the watch/read/write that shutdownmon does but if you find any bugs I can fix them.

What's missing though is a userspace library to do the dirty work for you, so you need to talk to the io interface directly. Have a look at the shutdownmon code.

No. What sort of use did you have in mind?

I want to able to send some command to userspace daemon, for example -
kill some task if the network (tcp/ip) not respond...

Can You provide some example of xs_write under windows ? What i need to
modify in xs_read of shutdownmon to write some info to xenstore?
