hi,:
I am a new user of libvirt ,I asked a question about using libvirt to connect to esxi
server. I got the answer is
https://www.redhat.com/archives/libvir-list/2012-February/msg00860.html
So,I try to make the change on the mailing list you just added.
- * Add a dummy expect header to stop CURL from waiting for a response code
+ * Add an empty expect header to stop CURL from waiting for a response code
- curl->headers = curl_slist_append(curl->headers, "Expect:
nothing");
+ curl->headers = curl_slist_append(curl->headers, "Expect:");
and I did the follow steps in my computer:
1../configure --with-esx
2.make
3.make install
4../autogen.sh --prefix=$HOME/usr
5.make
6.make install
I complete installing the libvirt and run the command :virsh --version ,get the right
answer 0.9.7
and I run the command :virsh -c esx://me@exampe.com/?tansport=http
the error before I mentioned related to http did disappeared ,but
and I still get a error like:error: internal error XPath evaluation of response for call
to 'RetrieveServiceContent' failed
I don't understand what does this error mean,or is my steps wrong ?so I hope you can
help me to figure out the promble. thanks a lot and so sorry for trouble you too much
.waiting for you reply on line.
ps: I have another question about libvirt , I saw this :%if %{with_esx}%if 0%{?fedora}
>= 9 || 0%{?rhel} >= 6 in /libvirt0.9.7/livirt.spec,I want to know if libvirt esx
driver only can be useful on fedora>=9||rhel>=6,and the other OS like centos 6.0 or
redhat ,will disable the use of esx driver of libvirt.
thanks again.
best regards!

hi,
I am a new user of libvirt ,i really appreciate libvirt，and want to use it
in my work.I want to use it to conncet to a ESXi server.when I try to
connect to the server ,I use the command :virsh -c
esx://name@exmaple.com,And I get an
1.error :error: internal error curl_easy_perform() returned an error:
Couldn't connect to server (7) : couldn't connect to host
so I think maybe the firewall shutdown the 443 for https,so I used
command:virsh -c esx://name@example.com/?transport=http And I still get an
error like:
error: internal error HTTP response code 417 for call to
'RetrieveServiceContent'
error: failed to connect to the hypervisor
HTTP error code 417 is related to the Expect header. The error
indicates that the server or a proxy in between doesn't handle the
Expect header. I assume that the ESXi sever itself is not the problem,
because it works for me here. Maybe there is a HTTP proxy between your
computer and the ESXi server that returns this 417 error code.
This problem is probably related to libvirt sending a dummy Expect
header instead of sending no Expect at all.
If you're building libvirt from source you can try this patch that I
just send to the mailing list for review
https://www.redhat.com/archives/libvir-list/2012-February/msg00860.html
It fixes the Expect header problem and might fix your connection problem.

The latest release is 0.9.10; if you still have problems, you might
want to consider upgrading before re-trying that patch.

Sorry, I don't know the answer to this one.
ps: I have another question about libvirt , I saw this :%if %{with_esx}%if 0%{?fedora}

driver only can be useful on fedora>=9||rhel>=6,and the other OS like centos 6.0 or

But I do know this - that is just stating that when building the RPM
files for the distro version of libvirt included in Fedora or RHEL, then
those are the distro defaults. That is, Fedora will default to ESX
support on, and RHEL 5 defaults to ESX off while RHEL 6 defaults to ESX
on. But those are defaults, and you can override them if you are
rebuilding the RPM yourself; furthermore, if you are building from the
tarball via a direct configure rather than trying to rebuild an RPM,
then the contents of the spec file don't matter (since they only affect
an RPM build).

This is bad. This means that your ESXi server has send an response
that libvirt does not understand.
I don't understand what does this error mean,or is my steps
wrong ?so I
hope you can help me to figure out the promble. thanks a lot and so sorry

I don't have enough information at hand to tell what is going wrong here.
You could provide more information by applying the attached patch to
your libvirt source code and recompile it. The patch enables complete
HTTP traffic logging. It makes libvirt output all its communication
with the ESXi server to the log.
Then run this command
LIBVIRT_DEBUG=1 LIBVIRT_LOG_OUTPUTS=1:file:esx_traffic.log virsh -c
esx://example.com/?transport=http
It'll output the debug information to a file named esx_traffic.log in
the current directory. If you mail me this log file I might be able to
figure out what the problem is.
Be aware that this log will contain your ESXi hostname, username and
password in clear text, so you might want to remove this information
from the log file before mailing it to the list.
ps: I have another question about libvirt , I saw this :%if
%{with_esx}%if
0%{?fedora} >= 9 || 0%{?rhel} >= 6 in /libvirt0.9.7/livirt.spec,I want to
know if libvirt esx driver only can be useful on fedora>=9||rhel>=6,and the
other OS like centos 6.0 or redhat ,will disable the use of esx driver of
libvirt.
As Eric explained this is basically a policy decision and is not
related to any problems with the ESX driver on older Fedora or RHEL
version.
I think your specific problem is in your specific network and/or ESXi
server setup and the traffic log might allow to reveal and fix it.

Matthias

HTTP error code 417 is related to the Expect header. The error
indicates that the server or a proxy in between doesn't handle the
Expect header. I assume that the ESXi sever itself is not the problem,
because it works for me here. Maybe there is a HTTP proxy between your
computer and the ESXi server that returns this 417 error code.
This problem is probably related to libvirt sending a dummy Expect
header instead of sending no Expect at all.

It fixes the Expect header problem and might fix your connection problem.
