[libvirt] RFC: whether or not to support multiple IDE controllers (and any IDE at all on Q35)
by Laine Stump 05 Apr '15

05 Apr '15

Due to a bug report by someone trying to add two cd drives to a Q35 domain in virt-manager (which assumes all CD drives are IDE), I've learned that libvirt doesn't support adding a "piix3-ide" controller when there is no ide controller for the domain (or when there are more than 4 disk devices that need to be connected to an IDE controller). It does dutifully add: <controller type='ide' index='n'/> as many times as necessary, it's just that there is no code behind that to add the device to the qemu commandline. I first thought I should add support for this, but then had second thoughts after following this reasoning: 1) I'm not sure exactly where the piix3-ide controller was added to qemu, but it was apparently sometime after qemu-1.2.0 (at least according to tests/qemuhelpdata/qemu-1.2.0-device). 2) At some point (again not sure, but it was there at least in qemu 1.0) support for a SATA controller was added (named ich9-achi by qemu), and it can also accept CD devices. So there is no version of qemu that has piix3-ide and no ich9-ahci. 3) "ide old, ahci new" 4) I'm doubtful there is any OS old enough to require an IDE disk controller rather than SATA that anyone would also want to put > 4 disk devices on. That leads me to think that maybe it is a better idea to just log an error if someone tries to add a disk with bus='ide' on a Q35 domain, or add more than 4 of them on an i440fx domain. Does anyone have an opinion, or (better yet) a smoking gun (e.g. problems with piix3-ide, or alternately problems with ahci or a situation where IDE would be required) that will force action in one direction or the other? (One possible example - although ahci was added on or before qemu 1.0, up until the most recent upstream it wasn't possible to migrate or save a domain with an ahci controller. Do we need to worry about people with qemu < 2.3.0 that want > 4 IDE devices? Or should we figure that if none have come up before now, likely none will come up in the future either?)

[libvirt] [PATCH] libvirt: virsh: Kill all uses of __FUNCTION__ in error messages
by Noella Ashu 04 Apr '15

04 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] 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 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.

[libvirt] [PATCH] virNetSocketNewConnectUNIX: Use flocks when spawning a daemon
by Michal Privoznik 02 Apr '15

02 Apr '15

https://bugzilla.redhat.com/show_bug.cgi?id=1200149 Even though we have a mutex mechanism so that two clients don't spawn two daemons, it's not strong enough. It can happen that while one client is spawning the daemon, the other one fails to connect. Basically two possible errors can happen: error: Failed to connect socket to '/home/mprivozn/.cache/libvirt/libvirt-sock': Connection refused or: error: Failed to connect socket to '/home/mprivozn/.cache/libvirt/libvirt-sock': No such file or directory The problem in both cases is, the daemon is only starting up, while we are trying to connect (and fail). We should postpone the connecting phase until the daemon is started (by the other thread that is spawning it). In order to do that, create a file lock 'libvirt-lock' in the directory where session daemon would create its socket. So even when called from multiple processes, spawning a daemon will serialize on the file lock. So only the first to come will spawn the daemon.

To be honest, calculating the CPU model name on the fly with strdup_s390_cpu_name() like you did above wouldn't be a problem to me. I just wanted to avoid having the same CPU model name logic (and special cases like "none") duplicated inside strdup_s390_cpu_name(), S390_PROC_DEF, s390_cpu_class_by_name(), and maybe other places. Maybe this duplication can be eliminated by simply reusing strdup_s390_cpu_name() inside s390_cpu_compare_class_name(). > > > I wonder if this class->model_name conversion could be made generic > > inside the CPU class.

It looks like we have conflicting expectations about query-cpu-definitions, it seems: on the one hand, if "-cpu none" is valid I believe it should appear on the query-cpu-definitions return value; on the other hand, it is not (always?) migration-safe, so just comparing the source query-cpus data with the target query-cpu-definitions data wouldn't be enough to ensure live-migration safety. On x86, we have a similar problem with "-cpu host", that changes depending on the host hardware and host kernel. We solve this problem by making libvirt code aware of the set of valid CPU models, and libvirt has special cases for "-cpu host". If you don't want to encode that knowledge in libvirt or other management software for s390, it looks like you need something like a "stable-abi-safe" field on CpuDefinitionInfo? > > > > > (I don't understand completely the meaning of "-cpu none" yet.

[libvirt] [PATCH 0/2] fix 2 bugs in virHostdevReAttachPCIDevices
by Huanle Han 02 Apr '15

02 Apr '15

Fix 1: Fix index error in loop after remove an element from the array 'virPCIDeviceList' is actually an array. Removing one element makes the rest of the element move. Use while loop, increase index only when not do 'virPCIDeviceListDel(pcidevs, dev)' Fix 2: In such a case: 1. Domain A and B xml contain the same SRIOV net hostdev(<interface type='hostdev' /> with same pci address). 2. virsh start A (Successfully, and configure the SRIOV net with custom mac) 3. virsh start B (Fail because of the hostdev used by domain A or other reason.) In step 3, 'virHostdevNetConfigRestore' is called for the hostdev which is still used by domain A. It makes the mac/vlan of the SRIOV net change. Code Change in this fix: 1. As the pci used by other domain have been removed from 'pcidevs' in previous loop, we only restore the nic config for the hostdev still in 'pcidevs'(used by this domain) 2. wrap a function 'virHostdevIsPCINetDevice', which detect whether the hostdev is a pci net device or not. 3. update the comments to make it more clear Huanle Han (2): hostdev: Fix index error in loop after remove an element hostdev: fix net config restore error src/util/virhostdev.c | 56 ++++++++++++++++++++++++++++++++++++--------------- 1 file changed, 40 insertions(+), 16 deletions(-) -- 1.9.1

[libvirt] [PATCH v2 0/6] storage: handle scsi/iscsi error paths better
by John Ferlan 02 Apr '15

02 Apr '15

v1 here: http://www.redhat.com/archives/libvir-list/2015-March/msg01562.html changes: 1/6: Removed the virGetLastError() == NULL check 2/6: New - reading more closely showed an error path without a goto 3/6: New - Adjust return for virStorageBackendSCSINewLun to be able to differentiate real error vs. deciding to return because a stable path could not be determined 4/6: New - Found an unused variable in processLU 5/6: Adjust the logic to return -1 for "real" errors and -2 for errors that are "recoverable". Removed the need for goto cleanup. 6/6: Add check for non-existent stable path at startup (and fail). Add check during refresh for a found non standard stable path that returns no volumes in the pool John Ferlan (6): iscsi: Use error message from virStorageBackendSCSIFindLUs iscsi: Fix exit path for virStorageBackendISCSIFindLUs failure scsi: Adjust return value for virStorageBackendSCSINewLun scsi: Remove unused 'type_path' in processLU scsi: Adjust return values from processLU iscsi: Add checks for non standard stable target.path src/storage/storage_backend_iscsi.c | 33 ++++++++++++++++----- src/storage/storage_backend_scsi.c | 59 ++++++++++++++++++++++++------------- 2 files changed, 64 insertions(+), 28 deletions(-) -- 2.1.0
