Libguestfs - Nov 2015 - Re: P2V conversion failed with "/run/lvm/lvmetad.socket: connect failed: No such file or directory"

Greetings Richard,

To add to the above information, we are following the understated steps:

   1. We have 2 BL460c (Gen8) with Fedora 21 installed. Both the
   machines(BL1 & BL2) have been updated with virt-v2v packages
   2. On BL1, we execute the following commands:
   1. virt-p2v-make-kickstart fedora
      2. livecd-creator p2v.ks
   3. After creating the "livecd-p2v-2xxxxxx.iso" file, we launch the
   'virt-manager', from BL1
   4. Create a new virtual machine using the 'File' option
   5. Click on 'Begin Installation' after step 4
   6. User is shown the 'Conversion Server' GUI login screen
   7. Enter the credentials & click on 'Test Connection with Conversion
   Server'
   8. 'Next' button is enabled
   9. Click on 'Create p2v' and after sometime, the process is exited
with
   status "-1"
   10. The earlier attached log file is generated in BL2 (conversion
   server) under /tmp/virt-XXXX directory

Hope it helps to solve the issue.


Regards,

Ravi Chaudhary

So hang on, you're running virt-p2v in a VM?

While we do sometimes run virt-p2v in a VM do operational testing of
P2V, this isn't the way to convert a physical machine.  You have to
burn the ISO to a CD and boot the physical machine using it.

(Alternatives exist: use livecd-iso-to-pxeboot; or possibly your blade
hardware will let you use the ISO directly as a virtual CD-ROM)

Anyway, running virt-p2v in a VM isn't going to work ...

Greetings Richard,

Thanks for the pointer. It was helpful. (Note: We have 2 physical machines,
one is p2v machine & the other is conversion server. Both the machines have
been updated with  "*yum install qemu libvirt-client virt-manager
virt-viewer guestfish libguestfs-tools virt-top*")

We have couple of questions for the exact functioning of virt-p2v:

   1. We are unable to locate the following command for injecting the ssh
   private key of p2v machine:

   *virt-p2v-make-kickstart p2v.ks --inject-ssh-identity id_rsa*

   *virt-p2v-make-kickstart: unrecognized option
'--inject-ssh-identity'*

   *virt-p2v-make-kickstart: problem parsing the command line arguments*
   2. *Further we are also unable to find any executable "virt-p2v" on
the
   p2v machine*
   3. *We are able to view the virt-p2v in GUI mode, only after booting the
   hardware using the ISO image, generated on p2v machine (The hardware used
   for booting is the same physical p2v machine). Is this the right way? We
   are observing the following error:*


*Would you be able to provide us with exact steps required to implement the
virt-p2v? *
