Description Daniel Qarras 2006-11-13 20:52:15 UTC
Description of problem: I was testing FC6/Xen on a laptop with 100GB HDD. I ran virt-install and accidentally gave disk size 2000 (gigabytes). virt-manager merrily continues its journey to install a virtual machine until it start formatting the / partition, it seems to take eons and will bring the system to its knees, nothing is responding under GNOME. After a forced reboot I found the disk image file being 2TB size(!). The same absurd behaviour can also be triggered with virt-manager. Version-Release number of selected component (if applicable): xen-3.0.3-0.1.rc3 kernel-xen-2.6.18-1.2849.fc6 virt-manager-0.2.3-2.fc6 libvirt-0.1.7-2 How reproducible: Always. Steps to Reproduce: 1. Create a new Xen virtual machine 2. Enter some hilarious disk size, e.g., 10 times your physical disk size 3. See the system crawling until the userr frustrates completely Actual results: System dying slowly. Expected results: Bizarre disk size rejected before proceding to OS install. Additional info: With sane disk size everything is working all ok.

To add confustion, virt-manager wants file size in megabytes, virt-install in gigabytes.
Comment 2 Jeremy Katz 2006-11-16 16:53:07 UTC
virt-manager should probably some sanity checking here and at least get confirmation; virt-install allows things like this somewhat intentionally (makes it easier to do testing of large disks, etc)
Comment 3 Hugh Brock 2007-06-18 18:21:45 UTC
Just to save me some testing, was the absurdly large storage file sparse or non-sparse? I assume non-sparse, but can you say for sure?
Comment 4 Daniel Qarras 2007-06-19 13:53:41 UTC
I can say for sure only that I was using default values and not doing any sparse settings by hand.

F6 is end of life, but this certainly should not be an issue in F7 or F8, as there is sanity checking in virt-install and virt-manager to ensure we do not attempt to create a disk that is larger than available space on the host. Closing this as CURRENTRELEASE.
