Re: Image Corruption Possible with qemu and qemu-kvm

i thought it might be good to post this on qemu-devel as well, as i see this as a general qemu / kvm / xen /whatevercomesnext issue .

are there any plans to implement a default in qemu to prevent accessing the same image multiple times ?
i know that in xen they deal with this problem somehow xen specific.
wouldn't it be good to prevent multiple access to the same image by default and add a switch to overwrite it ?

i am sure other people had the same issue as i had (corrupting images) and would be great to prevent people in the future messing around with data loss :-)

Image Corruption Possible with qemu and qemu-kvm






Hi,


i corrupted a couple of virtual Linux images last week as i accidentally started them two times ..

i opened a bug against qemu (not sure if this was a good idea) -->  
https://bugzilla.redhat.com/show_bug.cgi?id=253533

are there any plans to ensure that this can't happen in future releases of virt-manager with lock files in the image directory or similar ?


thanks. Sven
