Hi, I am adding a disk to my KVM virtual server, but for some reason it refuses to honor the <address> I have tried the following 3: <disk type='block' device='disk'> <driver name='phy' type='raw'/> <source dev='/dev/nbd2'/> <target dev='vdb' bus='virtio'/>

Hi, I am having 2 issues with disks and KVM. ISSUE 1: I am unable to detach a disk from a running KVM.

Hello, First of all, happy new year! I am interested in the hot plugging facilities of libvirt, in particular in what qemu calls 'hot add' of network interface cards. (And also the reverse: hot unplugging/removing of NICs.) I think I am overlooking something, but so far the best I have been able to find is: http://libvirt.org/sources/virshcmdref/html/ and it is not entirely clear

Instead of having to munge a URI to supply a different export name, we can exploit the fact that nbd_opt_mode lets us change the preferred export name after nbd_connect_uri has established its socket. In fact, by doing this, nbdinfo no longer needs to directly link against libxml2, so it can now be built regardless of whether the underlying libnbd.so supports URIs (although use of the program

I just noticed the entries on attach-disk and attach-devices are a bit on the empty size. As I am just attaching a usb device to one of my vm clients, I was wondering if I could offer examples to those entries.

Use the just-added nbd_opt_list_meta_context() API to give more details about each export (matching what 'qemu-nbd --list' already does). Note that this requires some shuffling: listing meta exports requires being in opt mode, but is easiest to do in list_one_export(), which requires setting opt_mode in more code paths, and deferring ready mode until the last possible minute during

I am experimenting with the blockcopy command, and after figuring out how to integrate qemu-nbd, nbd-client and dumpxml/undefine/blockcopy/define/et. al. I have one remaining question: What's the point? The "replication" disk file is not, from what I can ascertain, bootable. I expect this operation to create a pristine copy of my source qcow2 file (at a given point in time)

This replaces 13/13 of my v2 series; and now that it has pretty good testsuite coverage and demonstrable performance improvement to nbdinfo, I'm going ahead and pushing this now. We may still want to add further nbd_opt_* commands for other fine-grained tuning of negotiation, but for now, I think things have stabilized on this end, and I can return to polishing .list_exports on the nbdkit

Exposing a description in single mode is harder: we'd have to request NBD_INFO_DESCRIPTION during NBD_OPT_GO. For now, the API only supports descriptions in list mode. --- info/info-list-json.sh | 3 ++- info/info-list.sh | 3 ++- info/nbdinfo.c | 21 ++++++++++++++++----- 3 files changed, 20 insertions(+), 7 deletions(-) diff --git a/info/info-list-json.sh

Hi, I'm setting up Samba with ldap backend and everythin appears to be working correctly except for profiles. Using: samba-3.0.2 openldap-2.1.26 smbldap-tools-0.8.4 When a user 'testa' tries to logon from a Win2K system that has joined the domain he gets the following error message: "Windows did not load your roaming profile and is attempting to log you on with your local

Hi all, I have got 2 function (see bellow) which are simplifications of what I need to do. These functions are precisely the same, except for the last line. My question is, why doesn't function testA work in the same way as function testB. Both functions produce two objects, "a" and "b" that must merged with rbind. The difference is that in testA, I specify the name

Proposal for new APIs to list exports. The general shape of the API can probably best be seen from the examples/list-exports.c example. Rich.

A major missing feature of this library was the ability to list exports from an NBD server. This implements the feature by adding a new handle mode and additional functions for querying the list of export names. --- .gitignore | 1 + examples/Makefile.am | 14 +++ examples/list-exports.c | 108 +++++++++++++++++++

An incremental improvement on top of listing exports. I still think it's worth experimenting with revisiting how our API for list mode should actually work [1] (so that we can reuse a single connection for both grabbing the list and finally using NBD_OPT_GO), but this change was easier to whip together while still thinking about that.

Dear R gurus, I'm running into a problem with some modified segment plots I've coded using stars(). What I am trying to do is superimpose two series of data along with radial axes markers in a 2x2 graphics frame. This is working fine now, except for the hitch: my plots overfill the frame and are not centered within it (on my runs they always end up looking like they've been budged
