[libvirt] libvirt API to write sectors on a device
Hello,***I am able to compile libvirt samples on my KVM hypervisor. (I edited and recompiled info.c code) *I am creating a sample code to read/write disk devices. With method *virDomainBlockPeek I can** read sectors from a given device attached to a KVM virtual guest.**I am not able to* find an API to write sectors on a disk: am I missing something ?Is there such method to write sectors from a given virtual disk ? Thanks,Francesco

Hum, right, there is only read-only support since that's what was needed at the time. I'm not sure we should add unstructured write support like this, I don't know what you're trying to achieve but maybe libguestfs would be a better fit, have a look ! http://et.redhat.com/~rjones/libguestfs/ Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel@veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/
