Greetings:
Hello.
I have an issue with connecting to the esx hypervisor from my guest Vm. The purpose of the connection is to obtain host related information (like network, devices etc).
Unfortunately network and device enumeration is not implemented yet for the ESX driver.
I am not sure what is it that rejects the connect at the server side, and what i am missing.
I am running lib0.7.5, i have libvirtd running on guest-vm.
ESX support was added in 0.7.0, so your libvirt version is new enough. For ESX you don't need an libvirtd, neither on the client side nor on the server side, see http://libvirt.org/drvesx.html#prereq
The host ESX has the ip address a.b.c.d.
Any thoughts?
Are you sure that your libvirt was build with ESX support enabled? If you're using the Debian/Ubuntu packages that could be your problem, because they are build without ESX support. So you'll either need to file a bugreport with Debian/Ubuntu about the excluded ESX support, or build libvirt from source. If you're already building from source make sure to install the libcurl development package version 7.18.0 or newer, otherwise configure will disable ESX support.
Below the error with some debug output from libvirt.

Yep, your libvirt is build without ESX support. If it is enabled it would be probed before the remote driver.

The error message could be more explicit about the missing ESX support, I'll try to improve this.
error: failed to connect to the hypervisor
I tried to use uri like: esx://a.b.c.d/, esx://a.b.c.d, esxi://a.b.c.d/system etc. They all give same issue.
See http://libvirt.org/drvesx.html#uri for the URI format understood by the ESX driver, there is no distinction between /system and /session as with some other drivers. Matthias
