19:26 RFC configurable block formats Markus 23:27 ` Anthony Liguori If you agree this is useful, I'd be willing to code it. Then recognizing it in qemu proper shall be an error. If it is configured on for utility programs, off for qemu proper, If a format is configured off, no program shall recognize it.Įlse all programs shall recognize it, but Then I don't want qemu to silently treat qcow images as raw, I Say I configure crusty old qcow (note lack of 2) for utility programs If two programs have different sets ofĭrivers, probing may yield different results. Picks the one with the highest score (I'm simplifying, but it'll do to Probing gives every block driver a chance to "score" the image, and This leads to an unwanted difference in behavior between the different Thus, I'd like to be able to configure a block driver off forĮverything, or on for utility programs and off for qemu proper, or onĪ naive implementation of this idea simply links only those blockĭrivers into a program that have been configured for it.

Potential for mischief, to the formats I trust and need, and still keep Restrict qemu proper, where a faulty block driver has the greatest SimpleĮnough, eh? Except there's a catch: I'd like to be able to include moreįormats in tools like qemu-img than in qemu proper. In short, I'd like to be able to configure block formats. People in some circumstances, some of them are of a kind that friends While I trust that all of these formats are useful at least for some Only formats ftp, ftps, http, https, tftp are optional (see configure Https, nbd, parallels, qcow, qcow2, raw, tftp, vdi, vmdk, vpc, vvfat.
