Hello list! (resending, it seems the previous mail didn''t make it to the list) At some point Xen supported block-reconfigure to resize domU disks on the fly.. This is not working atm/anymore? Discussion about the subject.. (in the end of the thread): http://lists.xensource.com/archives/html/xen-users/2008-04/msg00246.html Support for online resizing Linux SCSI disks was accepted upstream recently: http://www.gossamer-threads.com/lists/linux/kernel/967628 That patch should end up in Linux 2.6.28. Anyone working to get Xen domU online disk resizing working again? -- Pasi _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Vendors can add/patch support for that if they feel like it.. ? -- Pasi _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Thanks! >In addition to pure PV guests, online resizing should be possible for HVM guests with PV-on-HVM drivers (supporthing this) installed.. ? How about pure HVM guests with only emulated disks and no PV drivers.. is online resizing possible there? -- Pasi _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
