Hello all

i download the puppet vm(ovf) and i want to run it in my current KVM:

So first i convert the vmdk:

qemu-img convert -f vmdk /dd/learn_puppet_centos-6.5-disk1.vmdk -O qcow2 /dd/learn_puppet_centos-6.5-disk1.qcow2


but fails: qemu-img: error while reading

i read somewhere that maybe is an error of the qemu-img.
Mine is from package kvm-qemu-img.

So i remove the kvm-qemu-img package and install qemu-img one, but the same error remains.

so, how can i convert the image?

regards

The latest version of qemu is 2.3.0. What version are you using?

also centOS 6.5 is and HAS been unsupported for a year

6.5 is missing a YEARS worth of security fixes

please upgrade to a supported version ASAP
6.6
but 6.7 should be out soon when that happens 6.6 will go End of Life

HI, i have a RHEL 5.5 and i download qemu-img from EPEL:

Version:
Installed Packages
Name : qemu-img
Arch : x86_64
Epoch : 2
Version : 0.10.5
Release : 1.el5.2
Size : 156 k
Repo : installed
Summary : QEMU command line tool for manipulating disk images
URL : http://www.qemu.org/


The VM is the one i download from puppet(is only for educational purposes) so no matter if is outdated.

Thanks both!

Perhaps a corrupted download(?).

Qemu-img is a stand alone part of qemu. As far as I know it doesn't interact with any other program.

Error should have more to it. Like error reading some thing.

There was a very old version that may have had an issue.

You should not go across directories too. Use the command in the directory where the input file exists. Better still move qemu-img there. I'd suspect this is the trouble. As I recall it got me a few times.


Simple examples.

Ok jefro, i tried as you said but same error persists.
If i convert to raw(with the "error while reading" error), it only create the 10gb sparse image file, so...i think in other options:


* use another version new version of qemu-img(by the way, why EPEL provides me the 2.1.0 version instead the last one?)

* use virtualbox, that is no compatible with KVM at the same time, so i have to convert my other VM to Vbox format. This VM disk is not a file but a device (dev/sdb)


any help with the two options?

regards

i try to download again...good point.

md5 is correct.

Oh you, we didn't read that. You said you downloaded an OVF? That shouldn't be a vmdk should it?

Hi jefro,

Puppet call it ovf(i think it must be an ova), and, when untar it is a vmdk and the xml desc. So i see no help in the links...or i lose something?

Thanks

I posted links to web pages of help.

Yes, you need to untar the file to get at vmdk.


Converting OVA to QCOW2 for use with QEMU/KVM

Extract the .ova file

$ tar -xvf file.ova

Convert the .vmdk to .qcow2

$ qemu-img convert -O qcow2 file.vmdk file.qcow2

Hello

Yes, this is what i did, and post in the first post.
The problem as you suggests is almost sure related with the qemu-img version. I saw several people complaining about this error and no solution, so maybe the best option is move to virtualbox.

regards

Pretty easy to get a different version of qemu-img.

Not sure I am totally sold on the problem being that version.


Get a different OVA and see if it works maybe. Guess you could even use windows version of qemu-img in wine to double check.


Where did you see that Version 2.x of qemu has issues?

well

maybe i tried with the wrong ones: the one in kvm-qemu-img that i have at begining, the one installed from EPEL(2.1.0) and the 0.14 i download from rpmfind.com for RHEL5.

Now i know that i could download QEMU from the web page and install ONLY the qemu-img binary...but too late....I moving to centos7 and i will try VBox.

wish me luck

regards

OK, thanks for the update. Sorry we didn't find a solution.
