Yes but raw data keeps the entire space so if you have a 40gb drive and only use 1gb you are stuck with 40gb. Whereas, qcow2 does not. Ciao Remo On Feb 6, 2014, at 9:50, Aryeh Friedman wrote: > qcow2 is almost certainly the worst choice here because if the hypervisor for > some reason become

Depends on your needs... if your only need is to save space then your right use qcow2 but if you have any need for stability or robustness use raw (qcow2 for example is much susceptible to the kinds of results like the one the original poster reported and later confirmed in the event of a unschedul

Oh forgot to mention depending on hypervisor qcow2 is *KNOWN* to have current (i.e. in the latest version) security flaws... see the qemu-developers list for detail https://lists.nongnu.org/mailman/listinfo/qemu-devel On Thu, Feb 6, 2014 at 9:50 AM, Aryeh Friedman wrote: > qcow2 is almost certai

qcow2 is almost certainly the worst choice here because if the hypervisor for some reason becomes unusable then the data is unreadable by some hypervisors... raw is much more portabls On Thu, Feb 6, 2014 at 9:19 AM, Bhattacharjee, Arindam (Arindam) < arindam.bhattachar...@alcatel-lucent.com> wrot

Probably you need to create qcow2 image out of iso image and then use that qcow2 to create VMs from Openstack. Follow the instructions similar to this: http://docs.openstack.org/image-guide/content/ubuntu-image.html From: Narayanan, Krishnaprasad [mailto:naray...@uni-mainz.de] Sent: Thursday, Fe
