[libvirt] [PATCH v4 RESEND] openvswitch: Add new port VLAN mode "dot1q-tunnel"(802.1ad double-tagged)
by luzhipeng＠uniudc.com 13 Feb '19

13 Feb '19

From: ZhiPeng Lu <luzhipeng(a)uniudc.com> This patch adds functionality to allow libvirt to configure the 'dot1q-tunnel' modes(802.1ad double-tagged) on openvswitch networks. For example: <interface type='bridge'> <mac address='2c:da:41:1d:05:42'/> <source bridge='ovs0'/> <vlan> <tag id='41' nativeMode='dot1q-tunnel'/> </vlan> <virtualport type='openvswitch'> <parameters interfaceid='6401a152-0b99-40b5-92be-858810aa6d37'/> </virtualport> <model type='virtio'/> <driver name='vhost'/> <alias name='net0'/> </interface> Signed-off-by: ZhiPeng Lu <luzhipeng(a)uniudc.com> --- v1->v2: 1.

[libvirt] [PATCH 00/10] snapshot: misc fixes
by Nikolay Shirokovskiy 05 Feb '19

05 Feb '19

The patch series aims to uniformly handle snapshot attribute for disks from multiple places - snapshot definitions, domain definitions, snapshot operation and defaults which is done in [1] utimately. Patch [2] makes a step towards this goal. Other patches are fixes along the way that disables some invalid cases on conversely enable previously disable valid cases. The patches with most reasoning ([2] and [3]) are effectively revert Eric's patch f9670bf thus I hope Eric will take a look. Nikolay Shirokovskiy (10): conf: snapshot: fix comment in _virDomainSnapshotDef conf: snapshot: don't pass flags from different family conf: snapshot: check disk with path on parse conf: snapshot: align exernal/internal snapshot the same way [2] conf: snapshot: remove snapshot mode checking from disk align [3] conf: virDomainSnapshotAlignDisks: use convinient variable qemu: disable internal snapshot of readonly disk qemu: snapshot: fix for case of disk with empty source qemu: snapshot: align disks consistently [1] conf: snapshot: make disk aligns same on redefinition src/conf/domain_conf.c | 6 +-- src/conf/snapshot_conf.c | 103 ++++++++++++++++++++++------------------------- src/conf/snapshot_conf.h | 5 +-- src/qemu/qemu_driver.c | 27 ++++++++++--- src/test/test_driver.c | 5 +-- 5 files changed, 74 insertions(+), 72 deletions(-) -- 1.8.3.1

[libvirt] [PATCH] network: set mtu as a DHCP option when specified
by Casey Callendrello 31 Jan '19

31 Jan '19

This adds an additional directive to the dnsmasq configuration file that notifies clients via dhcp about the link's MTU. Guests can then choose adjust their link accordingly.

[libvirt] [PATCH 00/27] network: refactor to decouple virt drivers from network driver
by Daniel P. Berrangé 31 Jan '19

31 Jan '19

Currently the network driver registers a set of callbacks with the virt driver in order to handle allocating/releasing network ports associated with guest NICs. This series introduces a virNetworkPortPtr object and associated XML that describes a network port. The virt drivers now call public APIs associated with this new object to create/delete ports for guest NICs. There are some parts that are not yet addressed by this series - The live updating of bandwidth limits on network ports - The old code would re-connect VIFs to bridges, and/or change bridges during startup. This code is deleted right now as it doesn't belong in the network driver. It needs to move to the virt drivers in some (to be determined) manner. Daniel P.

[libvirt] [PATCH v2 0/4] Restructure firewall rules for virtual networks into private chains
by Daniel P. Berrangé 24 Jan '19

24 Jan '19

v1: https://www.redhat.com/archives/libvir-list/2018-November/msg00018.html The virtual networks in NAT mode are supposed to only allow outbound network access for guests. Unfortunately due to ordering of the firewall rules libvirt creates, when you have multiple virtual networks, guests on the more recently created virtual networks can connect to guests on old virtual networks. This was reported way back in 2008 but we always thought the fix would be very complicated to deal with, so we've been putting it off forever. In parallel with this there's also been a long standing desire since 2009 to move our firewall rules out of the builtin chains, to libvirt private chains. This is to make it easier for admins to use hook scripts to setup rules in the builtin chains that take priority over rules libvirt creates. In implementing the changes to use private chains, I suddenly realized that fixing the network to network traffic blocking problem was trivial if I grouped the forwarding rules into three distinct sets. So this series finally fixes an annoying 10 year old bug, and implements a 9 year old RFE. It may take us a while, but we'll get to your bugs eventually ;-) Changed in v2: - Detect whether chains already exist before creating them - Only try to delete legacy rules from builtin chain during startup Daniel P.

[libvirt] [PATCH] storage: More uniquely identify NPIV LUNs
by John Ferlan 18 Jan '19

18 Jan '19

https://bugzilla.redhat.com/show_bug.cgi?id=1657468 Commit be1bb6c95 changed the way volumes were stored from a forward linked list to a hash table. In doing so, it required that each vol object would have 3 unique values as keys into tables - key, name, and path. Due to how vHBA/NPIV LUNs are created/used this resulted in a failure to utilize all the LUN's found during processing. The virStorageBackendSCSINewLun uses virStorageBackendSCSISerial in order to read/return the unique serial number of the LUN to be used as a key for the volume. However, for NPIV based LUNs the logic results in usage of the same serial value for each path to the LUN. For example, $ lsscsi -tg ... [4:0:3:13] disk fc:0x207800c0ffd79b2a0xeb02ef /dev/sde /dev/sg16 [4:0:4:0] disk fc:0x50060169446021980xeb1f00 /dev/sdf /dev/sg17 [4:0:5:0] disk fc:0x50060161446021980xeb2000 /dev/sdg /dev/sg18 ... /lib/udev/scsi_id --replace-whitespace --whitelisted --device /dev/sde 3600c0ff000d7a2965c603e5401000000 /lib/udev/scsi_id --replace-whitespace --whitelisted --device /dev/sdf 350060160c460219850060160c4602198 /lib/udev/scsi_id --replace-whitespace --whitelisted --device /dev/sdg 350060160c460219850060160c4602198 The /dev/sdf and /dev/sdg although separate LUNs would end up with the same serial number used for the vol->key value. When attempting to add the LUN via virStoragePoolObjAddVol, the hash table code will indicate that we have a duplicate: virHashAddOrUpdateEntry:341 : internal error: Duplicate key and thus the LUN is not added to the pool. Digging deeper into the scsi_id output using the --export option one will find that the only difference between the two luns is: ID_TARGET_PORT=1 for /dev/sdf ID_TARGET_PORT=2 for /dev/sdg So, let's use the ID_TARGET_PORT string value along with the serial to generate a more unique key using "@serial_PORT@target_port", where @target_port is just the value of the ID_TARGET_PORT for the LUN.

[libvirt] [PATCH RFC 00/51] refactor block job handling and add support for new event/commands (blockdev-add saga)
by Peter Krempa 17 Jan '19

17 Jan '19

This series refactors how libvirt stores block job data and handles block job events in general. This is done in preparation for -blockdev support where we'll need to add support for the 'blockdev-create' job which is not associated to any frontend 'disk' in some cases. This series introduces a new structure and table of blockjobs currently running and implements handlers for the new even "JOB_STATUS_CHANGE". RFC status excuses: - the series needs much more testing than I did - the last few patches are true RFC - I didn't port/refactor the rest of the blockjob finishing code that I have for the individual job types after the big refactor so there aren't any examples for the -blockdev case yet. I'll post the link to a repo containing the patches some time later.

[libvirt] [PATCH] qemu: Update a domain's persistent definition file if it's defined
by Wang Yechao 17 Jan '19

17 Jan '19

From: Li XueLei <li.xuelei1(a)zte.com.cn> During making disk snapshot in an active domain, sometimes we should update the domain's persistent definition.We must check if the domain is defined, before we update the persistent definition file. First,we create a vm.Then,define the vm and undefine the vm.Last create a --memspec snapshot for the vm.Now,we will find a persistent definition file in the config directory if we don't use this patch.
