Finding out if Xen or KVM is used
I've got 2 doubts:
1.I've been trying to write an application using Libvirt's Java API which
should run on both Xen and KVM running machines and execute the Xen or KVM
code based on the hypervisor used. I want the physical machine to know if
it's running Xen or KVM and execute only that code.
While using getURI(), I need to use it as
conn.getURI()
but then I can't use conn

Problem with listDomains() in Xen
This question concerns the usage of the listDomains(). When I run this
piece of code in KVM, it works perfectly fine but throws an array out of
bounds exception in Xen.
Connect conn=null;
conn = new Connect("xen:///", true);
int[] id = conn.listDomains();
System.out.println("lD of VM " +id[0]);
Answer I'd got:
Well, your code assumes that id.length is >= 1, but

libvir: Remote error : cannot recv data: : Connection reset by peer
I'm using Libvirt's Java API and connecting to the hypervisor using the
same. My program is such that periodic discovery of active VMs is done using
Libvirt's functions.
However, when I try to perform any VM related operations while the Java code
connecting to Qemu is running such as shutdown, start VM using virsh, I end
up with :

Checking if the VM has been created
I'm a Libvirt newbie and I'd really appreciate it if someone could answer
my doubts. I'm using Libvirt's Java API.
My doubts:
1.Currently, I'm able to create a VM on Ubuntu 11.04 using Libvirt
functions domainCreateLinux() and domainDefineXML(). Apart fromt the
boolean return status of these operations and running the virsh list
command, is there any way to SSH in (login) to

ESX VM from scratch
I want to create a virtual machine from scratch in ESX but I can't figure
out how to create the disks - the vmdk files. Any hints on how that can be
done or even if it's possible at all ?

Libvirt newbie, need help with doubts
Hi,
These are my doubts:
1. I tried live migration of Ubuntu 11.04 from the one physical machine to
another using the migrate() function. I connected via tcp in the destination
URI and migrated successfully(lesser than 2 seconds). I tried running virsh
list --all on the destination PM and confirmed that the VM had been migrated
successfully.

libvirt and VMWare Workstation Shared Server mode (of GSX history)
Hi everyone,
I searched previous postings and I couldn't find a definitive answer on
this..
I run a small lab of RHEL/Centos Based servers on which there's VMWare
Workstation running on a non-standard port but still manageable by tools
like VMrun (and the Fusion of Workstation GUI, of course).

Re: Using certtool to generate certificates for ESXi
Hi Daniel,
thanks for the reply - The procedure I use is the same as I use for
XenServer, and the certificate exchange works just fine. The only thing
I'm a bit unclear on, is the location of the CA cert, which in the case of
XenServer, I simply put it in /etc/pki/CA. And when I start the libvirtd
daemon, it successfully picks it up. If I put the Server key and cert in
/etc/vmware/ssl for

Live Migration using Libvirt migrate()
Hi,
This is a follow up of the mail regd migration I'd posted a few days ago. My

I'm creating two virtual machines images from an Ubuntu 10.10 iso of RAM
size 128 and 700 MB.
Using the migrate() , I migrate it from the current physical machine to the
destination machine via a 100 Mbps switch LAN connection. BOTH migrations
take the same amount of time.
