[libvirt] Entering freeze for libvirt-1.2.14
by Daniel Veillard 03 Apr '15

03 Apr '15

I have tagged a release candidate 1 in git and generated signed tarballs and rpms at the usual place: ftp://libvirt.org/libvirt/ This seems to work normally in my limited testing but others need to give it a serious try ! I think I will do an RC2 on Monday, and if everything look file the final release will be on April 1st. Thanks in advance for reports about it !

[libvirt] [PATCH] libvirt: virsh: Kill all uses of __FUNCTION__ in error messages
by Noella Ashu 03 Apr '15

03 Apr '15

The error output of snapshot-revert should be more friendly. There is no need to show up virDomainRevertToSnapshot to user. virError already includes __FUNCTION__ information in a separate member of the struct, so repeating it in the message is redundant and leads to situations where higher level code ends up reporting the lower level name We correctly converted the error output making it more succinct and user-friendly.

[libvirt] [PATCH 0/2] esx: Make esxNodeGetFreeMemory always use ESX host.
by Dawid Zamirski 03 Apr '15

03 Apr '15

This patch is intended to make ESX driver behave more consistently. When calling virNodeGetFreeMemory, it would return the free bytes from a cluster when using vpx connection or ESX host when using esx connection. However, virGetNodeInfo always returns info from ESX host (specifying ESX host is mandatory, even for vpx connections) so to make this consitent, these patches make virNodeGetFreeMemory always return info from the ESX host.

[libvirt] qemu: migration: continuously sending and receiving ARP packets guest mistakenly thinks there's another guest with the same IP.
by zhang bo 03 Apr '15

03 Apr '15

Problem Description: Live-migrate a guest, which has a tap device and continuously sends and receives ARP packets, it would mistakenly think there's another guest with the same IP, immedially after migration. The steps to reproduce the problem: 1 define and start a domain with its network configured as: <interface type='bridge'> <mac address='52:54:00:7d:b0:af'/> <source bridge='br0'/> <virtualport type='openvswitch'> <parameters interfaceid='e4ad3dbb-7808-4175-83ee-ee0cba1c5456'/> </virtualport> <model type='virtio'/> <driver name='vhost' queues='4'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> 2 The guest sends ARP packets continuously: arping -I ethX xx.xx.xx.xx(self_ip) 3 Meanwhile, the guest also receives ARP packets continuously: tcpdump -i ethX arp host xx.xx.xx.xx(self_ip) -entttt 4 After migrateion, at the dest side, the guest gets a lot of ARP packets which came from the source-side guest(which was stored while it's suspended.). For example: 2015-03-27 16:45:56.695166 52:54:00:7d:b0:af > ff:ff:ff:ff:ff:ff, ethertype ARP (0x0806), length 60: arp who-has 9.61.108.208 (ff:ff:ff:ff:ff:ff) tell 9.61.108.208 2015-03-27 16:45:56.695197 52:54:00:7d:b0:af > ff:ff:ff:ff:ff:ff, ethertype ARP (0x0806), length 60: arp who-has 9.61.108.208 (ff:ff:ff:ff:ff:ff) tell 9.61.108.208 2015-03-27 16:45:56.695205 52:54:00:7d:b0:af > ff:ff:ff:ff:ff:ff, ethertype ARP (0x0806), length 60: arp who-has 9.61.108.208 (ff:ff:ff:ff:ff:ff) tell 9.61.108.208 2015-03-27 16:45:56.695214 52:54:00:7d:b0:af > ff:ff:ff:ff:ff:ff, ethertype ARP (0x0806), length 60: arp who-has 9.61.108.208 (ff:ff:ff:ff:ff:ff) tell 9.61.108.208 2015-03-27 16:45:56.695244 52:54:00:7d:b0:af > ff:ff:ff:ff:ff:ff, ethertype ARP (0x0806), length 60: arp who-has 9.61.108.208 (ff:ff:ff:ff:ff:ff) tell 9.61.108.208 2015-03-27 16:45:56.695256 52:54:00:7d:b0:af > ff:ff:ff:ff:ff:ff, ethertype ARP (0x0806), length 60: arp who-has 9.61.108.208 (ff:ff:ff:ff:ff:ff) tell 9.61.108.208 2015-03-27 16:45:56.695264 52:54:00:7d:b0:af > ff:ff:ff:ff:ff:ff, ethertype ARP (0x0806), length 60: arp who-has 9.61.108.208 (ff:ff:ff:ff:ff:ff) tell 9.61.108.208 2015-03-27 16:45:56.695291 52:54:00:7d:b0:af > ff:ff:ff:ff:ff:ff, ethertype ARP (0x0806), length 60: arp who-has 9.61.108.208 (ff:ff:ff:ff:ff:ff) tell 9.61.108.208 2015-03-27 16:45:56.695324 52:54:00:7d:b0:af > ff:ff:ff:ff:ff:ff, ethertype ARP (0x0806), length 60: arp who-has 9.61.108.208 (ff:ff:ff:ff:ff:ff) tell 9.61.108.208 2015-03-27 16:45:56.695337 52:54:00:7d:b0:af > ff:ff:ff:ff:ff:ff, ethertype ARP (0x0806), length 60: arp who-has 9.61.108.208 (ff:ff:ff:ff:ff:ff) tell 9.61.108.208 2015-03-27 16:45:56.695344 52:54:00:7d:b0:af > ff:ff:ff:ff:ff:ff, ethertype ARP (0x0806), length 60: arp who-has 9.61.108.208 (ff:ff:ff:ff:ff:ff) tell 9.61.108.208 2015-03-27 16:45:56.695364 52:54:00:7d:b0:af > ff:ff:ff:ff:ff:ff, ethertype ARP (0x0806), length 60: arp who-has 9.61.108.208 (ff:ff:ff:ff:ff:ff) tell 9.61.108.208 5 These packets will confuse my process. It may think that there is another VM has the same IP with itself. Reasons for the problem: The tap device will get up as soon as it's created(in virNetDevTapCreateInBridgePort), before the cpus got un-paused. So, it kept receiving data before the guest starts to run, please note that the data are sent from the source side. As soon as the guest get running, it parses the data stored before, and thinks they were from other guest with the same IP, which is in fact the guest from the source side. There was a patch "network: Bring netdevs online later", it move the virNetDevSetOnline() of network device just before start VM's vcpu. But in the Laine Stump replay mail say "It turns out, though, that regular tap devices which will be connected to a bridge should be ifup'ed and attached to the bridge as soon as possible, so that the forwarding delay timer of the bridge can start to count down." I agree with Laine Stump's idea that it's not a perfect solution to start the tap device right before running vcpu. so, here comes the question: what can we do to insure our guests not receive itself's ARP packets from src side during migrateion?

[libvirt] [PATCH 0/3] REWORK/REPOST: Refactor some qemuDomainHotplugVcpus code
by John Ferlan 03 Apr '15

Originally these were in the middle of the IOThreads Setting code that needs some rework. So rather than needing to have to continually merge changes in this space, I separated them out. These are (hopefully) pure code motion and will be used in some manner by changes that will come this release cycle for IOThread Add/Del Support. IOThreads's posting: http://www.redhat.com/archives/libvir-list/2015-March/msg01014.html and specifically in order: http://www.redhat.com/archives/libvir-list/2015-March/msg01017.html http://www.redhat.com/archives/libvir-list/2015-March/msg01018.html http://www.redhat.com/archives/libvir-list/2015-March/msg01019.html I did have to make some changes to the last one to account for other recent changes in the code John Ferlan (3): qemu: qemuDomainHotplugVcpus - separate out the add cgroup qemu: qemuDomainHotplugVcpus - separate out the del cgroup and pin qemu: qemuDomainHotplugVcpus - separate out pin adjustment code src/qemu/qemu_driver.c | 201 ++++++++++++++++++++++++++++++++----------------- 1 file changed, 130 insertions(+), 71 deletions(-) -- 2.1.0

[libvirt] [PATCH V3] libxl: fix dom0 balloon logic
by Jim Fehlig 02 Apr '15

02 Apr '15

Recent testing on large memory systems revealed a bug in the Xen xl tool's freemem() function. When autoballooning is enabled, freemem() is used to ensure enough memory is available to start a domain, ballooning dom0 if necessary. When ballooning large amounts of memory from dom0, freemem() would exceed its self-imposed wait time and return an error. Meanwhile, dom0 continued to balloon. Starting the domain later, after sufficient memory was ballooned from dom0, would succeed. The libvirt implementation in libxlDomainFreeMem() suffers the same bug since it is modeled after freemem(). In the end, the best place to fix the bug on the Xen side was to slightly change the behavior of libxl_wait_for_memory_target(). Instead of failing after caller-provided wait_sec, the function now blocks as long as dom0 memory ballooning is progressing. It will return failure only when more memory is needed to reach the target and wait_sec have expired with no progress being made. See xen.git commit fd3aa246. There was a dicussion on how this would affect other libxl apps like libvirt http://lists.xen.org/archives/html/xen-devel/2015-03/msg00739.html If libvirt containing this patch was build against a Xen containing the old libxl_wait_for_memory_target() behavior, libxlDomainFreeMem() will fail after 30 sec and domain creation will be terminated. Without this patch and with old libxl_wait_for_memory_target() behavior, libxlDomainFreeMem() does not succeed after 30 sec, but returns success anyway. Domain creation continues resulting in all sorts of fun stuff like cpu soft lockups in the guest OS. It was decided to properly fix libxl_wait_for_memory_target(), and if anything improve the default behavior of apps using the freemem reference impl in xl. xl was patched to accommodate the change in libxl_wait_for_memory_target() with xen.git commit 883b30a0. This patch does the same in the libxl driver. While at it, I changed the logic to essentially match freemem() in $xensrc/tools/libxl/xl_cmdimpl.c. It was a bit cleaner IMO and will make it easier to spot future, potentially interesting divergences.
