[libvirt-users] Using certtool to generate certificates for ESXi
by Shiva Bhanujan
Hello,
I'm using certtool to generate the server certificates for ESXi -
http://libvirt.org/remote.html#Remote_TLS_CA. I just copy the server
certificate and key as /etc/vmware/ssl/rui.crt and /etc/vmware/ssl/rui.key.
And then use virsh to connect from a CentOS 6.4 VM running on it - "virsh
-c esx://<esx IP>. I get the following error -
error: internal error curl_easy_perform() returned an error: Peer
certificate cannot be authenticated with known CA certificates (60) : Peer
certificate cannot be authenticated with known CA certificates
error: failed to connect to the hypervisor
is there something basic that I'm missing?
Regards,
Shiva

I have tried this command on libvirt v1.1.3 and it returns "error:
invalid argument: qemuDomainSnapshotCreateXML: unsupported flags
(0x100)". Looks like --live is not supported yet. Could you let us
know which version we should of libvirt we should use in order to use
this feature?
Thanks,

[libvirt-users] Fwd: Help regarding virsh domifstat
by Rohit Bhat
Hi,
I need a small help. I am working on a project where i have to monitor
network activity of a VM running on KVM.
I am interested in how much data is going into the VM and how much
data is coming out of the VM. I checked on the net and found out virsh
domifstat is the way to go about it.
1. But looks like these stats also include bytes related to control
traffic for the VM. Is there a way to exclude that? I just want the
size of actual data transfers.
2. Is there a way by which i can report the data transfer of VM with
the outside world (outside hypervisor) only while excluding data
transfer with any other VM on the same host or with the host itself?
Thanks,
Rohit
