[Xen-devel] [PATCH] Fix xm block-configure

[Masaki Kanno <kanno.masaki@xxxxxxxxxxxxxx>]

Hi,

This patch solves problems of xm block-configure command.

In the case of inactive managed domains:
 The following error occurs currently.  We cannot change the configuration 
 of the VBD by using xm block-configure.  Of course, using xm block-detach 
 and xm block-attach instead of xm block-configure, we can change it.
 However, I'd like to change it by using xm block-configure.
 
 # xm block-list vm1
 Vdev  BE handle state evt-ch ring-ref BE-path
 5632   -1   0     -1     -1     -1    ??                              
 # xm block-configure vm1 file:/var/xen/boot.iso hdc:cdrom r
 Error: Device 5632 not connected
 Usage: xm block-configure <Domain> <BackDev> <FrontDev> <Mode> [BackDomain]
 
 Change block device configuration


In the case of active domains:
 Another problem occurs after a domain was rebooted.  Even if we change 
 a configuration of a VBD in the domain by using xm block-configure, the 
 configuration of the VBD is reverted to previous configuration after the 
 domain was rebooted.
