libvirt users - Apr 2015 - Re: [Libvirt] [virsh] Transport Error during enumeration while connecting libvirt to Hyper-V Server

Hi all,

I am using libvirt 1.1.1. I can successfully able to connect with Qemu driver
but when I am trying to connect to the windows Hyper-V using virsh, I am getting
failure.

[root@localhost hyperv]# virsh version
Compiled against library: libvirt 1.1.1
Using library: libvirt 1.1.1
Using API: QEMU 1.1.1
Running hypervisor: QEMU 1.5.3

When I am doing virsh to connect to hype-V  I am getting failure that


[root@localhost hyperv]# virsh -c hyperv://172.16.67.192
Enter username for 11.16.67.92 [administrator]: administrator
Enter administrator's password for 11.16.67.92:
error: failed to connect to the hypervisor
error: internal error: Transport error during enumeration: Transport
initialization failed (2)

using gdb I came to know that from the function "hypervEnumAndPull()"
it is calling "wsmc_action_enumerate()"
and we are verifying the response using "hyperyVerifyResponse" and
from there it fails and cleanup is being called.

Code :

response = wsmc_action_enumerate(priv->client, root, options, filter);

    if (hyperyVerifyResponse(priv->client, response, "enumeration")
< 0) {
        goto cleanup;
    }


I have correctly done the settings on my hyper-v Server using below commands:
winrm set winrm/config/service/auth @{Basic="true"}

winrm set winrm/config/service @{AllowUnencrypted="true"}


Does anyone knows what could be wrong or  I am missing something or can anyone
help to solve this issue.

Thanks & Regards,

libvirt uses openwsman to talk to Hyper-V. openwsman internally uses libcurl.

This error means that openwsman reported WS_LASTERR_FAILED_INIT. This
error code means that the libcurl call curl_easy_init() failed.

This seems to me like a openwsman/libcurl issue, not related at all to
the actual Hyper-V server you try to connect to.

Unfortunately, I'm not sure how to debug this problem.

What openwsman and libcurl version are installed?

Hi Matthias,
