[libvirt] [PATCH] Add -nodefconfig to the QEMU argv
by Daniel P. Berrange 12 Jun '10

12 Jun '10

We already use the '-nodefaults' command line arg with QEMU to stop it adding any default devices to guests. Unfortunately, QEMU will load global config files from /etc/qemu that may also add default devices. These aren't blocked by '-nodefaults', so we need to also add the '-nodefconfig' arg to prevent that. Unfortunately these global config files are also used to define custom CPU models. So in blocking global hardware device addition we also block definitions of new CPU models. Libvirt doesn't know about these custom CPU models though, so it would never make use of them anyway. Thus blocking them via -nodefconfig isn't a show stopping problem. We would need to expand libvirt's own CPU model XML database to support these instead. * src/qemu/qemu_conf.c: Add '-nodefconfig' if available * tests/qemuxml2argvdata/: Add '-nodefconfig' to all data files which have '-nodefaults' present --- src/qemu/qemu_conf.c | 6 ++++-- .../qemuxml2argv-channel-guestfwd.args | 2 +- .../qemuxml2argv-channel-virtio-auto.args | 2 +-

[libvirt] [PATCHv2-resend] uml: sanity check external data before using it

Otherwise, a malicious packet could cause a DoS via spurious out-of-memory failure. * src/uml/uml_driver.c (umlMonitorCommand): Validate that incoming data is reliable before using it to allocate/dereference memory.

If I don't use the --match target on this tcp port 22 rule, I could initiate traffic inside the VM from TCP port 22 (client port) towards an allowed target. If the --match NEW, ESTABLISHED target is added on incoming traffic, I get control over directionality due to the NEW. The outgoing direction will then have --match ESTABLISHED. Since the NEW will be missing on outgoing traffic, I won't be able to initiate that traffic. In essence it's iptables -p tcp --dport 22 -j ACCEPT versus iptables -p tcp --dport 22 -m state --state NEW, ESTABLISHED > Regards, > Daniel >

[libvirt] [PATCH] nwfilter: add XML attribute to control match target
by Stefan Berger 11 Jun '10

11 Jun '10

This patch adds an optional XML attribute to a nwfilter rule to give the user control over whether the rule is supposed to be using the match target or not. A rule may now look like as follows with the nomatch attribute either having value '1' or 'true' (case-insensitive). [...] <rule action='accept' direction='in' nomatch='true'> <tcp srcmacaddr='1:2:3:4:5:6' srcipaddr='10.1.2.3' srcipmask='32' dscp='33' srcportstart='20' srcportend='21' dstportstart='100' dstportend='1111'/> </rule> [...] I am also extending the nwfilter schema and add this attribute to a test case.

[libvirt] Planning for libvirt-0.8.2 release
by Daniel Veillard 11 Jun '10

11 Jun '10

As some may have noticed I'm a bit away from the list, and will still for one more week. If we want to plan for a friday 25 release as suggested a couple of week ago this means we have one more week for commiting big changes (e.g. the new CreateWithFlags API but that looks uncontroversial), and start the freeze week next Friday the 18th. I didn't see anything big which may need more than one more week of devel and need pushing on 0.8.2, but maybe I overlooked something, in which case please tell me :-) Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel(a)veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/

[libvirt] wrong path of domblkstat
by jbuy0710 11 Jun '10

11 Jun '10

Hi all: I tried to use virsh domblkstat to get block information of a vm(xen para-virtualized), and it returns error message like this error: Failed to get block stats vm1 hda error: internal error read_bd_stats: Failed to read any block statistics I found the code in \src\xen\block_stats.c is wrong in line 121 "/sys/devices/xen-backend/vbd-%d-%d/statistics/%s", should be "/sys/devices/vbd-%d-%d/statistics/%s", in line 127 should be "/sys/devices/tap-%d-%d/statistics/%s", After modified and rebuild the soure code,the domblkstat can work fine. Anyone can help to update the code in the git?

[libvirt] [PATCHv3 1/2] virsh: add pool support to vol-key command
by Justin Clift 11 Jun '10

11 Jun '10

Presently the vol-key command only supports being provided with a volume path. This patch adds support for providing it with a pool and volume identifier pair as well. virsh # vol-key --pool <pool-name-or-uuid> <vol-name-or-path> --- This is a clean patch against current git head, plus avoids a potential memory leak in the v1 code. It's identical to the v2 code, except now I may have the PATCHv3 subject prefix correct. :) Also unlike the v1 patch, this one doesn't change the help text for other volume commands. The patch following this one addresses the help text of the vol-name and vol-path commands. tools/virsh.c | 6 +++--- tools/virsh.pod | 7 ++++--- 2 files changed, 7 insertions(+), 6 deletions(-) diff --git a/tools/virsh.c b/tools/virsh.c index 546e247..db8b28d 100644 --- a/tools/virsh.c +++ b/tools/virsh.c @@ -6032,12 +6032,13 @@ cmdVolPool(vshControl *ctl, const vshCmd *cmd) * "vol-key" command */ static const vshCmdInfo info_vol_key[] = { - {"help", N_("convert a vol UUID to vol key")}, + {"help", N_("returns the volume key for a given volume name or path")}, {"desc", ""}, {NULL, NULL} }; static const vshCmdOptDef opts_vol_key[] = { + {"pool", VSH_OT_STRING, 0, N_("pool name or uuid")}, {"vol", VSH_OT_DATA, VSH_OFLAG_REQ, N_("vol uuid")}, {NULL, 0, 0, NULL} }; @@ -6050,8 +6051,7 @@ cmdVolKey(vshControl *ctl, const vshCmd *cmd) if (!vshConnectionUsability(ctl, ctl->conn, TRUE)) return FALSE; - if (!(vol = vshCommandOptVolBy(ctl, cmd, "vol", "pool", NULL, - VSH_BYUUID))) + if (!(vol = vshCommandOptVol(ctl, cmd, "vol", "pool", NULL))) return FALSE; vshPrint(ctl, "%s\n", virStorageVolGetKey(vol)); diff --git a/tools/virsh.pod b/tools/virsh.pod index b54003c..f6d7808 100644 --- a/tools/virsh.pod +++ b/tools/virsh.pod @@ -855,10 +855,11 @@ I<vol-name-or-key> is the name or key of the volume to return the path for.

[libvirt] [PATCHv3 0/2] virsh: add pool support to vol-key, plus help text fix
by Justin Clift 11 Jun '10

11 Jun '10

Hi all, The following two patches are a resubmission. The first adds --pool support to the vol-key command. The seconds improves the help text for the vol-name, vol-path, and vol-key commands. Hopefully now I have the patch prefix correct as well. :) Regards and best wishes, Justin Clift -- Salasaga - Open Source eLearning IDE http://www.salasaga.org
