[libvirt] [PATCH] storage: Don't do wait loops from VolLookupByPath
by Cole Robinson 23 Oct '12

23 Oct '12

virStorageVolLookupByPath is an API call that virt-manager uses quite a bit when dealing with storage. This call use BackendStablePath which has several usleep() heuristics that can be tripped up and hang virt-manager for a while. Current example: an empty mpath pool pointing to /dev/mapper makes _any_ calls to virStorageVolLookupByPath take 5 seconds. The sleep heuristics are actually only needed in certain cases when we are waiting for new storage to appear, so let's skip the timeout steps when calling from LookupByPath. --- src/storage/storage_backend.c | 12 ++++++++---- src/storage/storage_backend.h | 3 ++- src/storage/storage_backend_disk.c | 2 +- src/storage/storage_backend_scsi.c | 3 ++- src/storage/storage_driver.c | 3 ++- 5 files changed, 15 insertions(+), 8 deletions(-) diff --git a/src/storage/storage_backend.c b/src/storage/storage_backend.c index aea70e2..85b8287 100644 --- a/src/storage/storage_backend.c +++ b/src/storage/storage_backend.c @@ -1338,10 +1338,14 @@ virStorageBackendDetectBlockVolFormatFD(virStorageVolTargetPtr target, * * Typically target.path is one of the /dev/disk/by-XXX dirs * with stable paths. + * + * If 'wait' is true, we use a timeout loop to give dynamic paths + * a change to appear. */ char * virStorageBackendStablePath(virStoragePoolObjPtr pool, - const char *devpath) + const char *devpath, + bool wait) { DIR *dh; struct dirent *dent; @@ -1372,7 +1376,7 @@ virStorageBackendStablePath(virStoragePoolObjPtr pool, reopen: if ((dh = opendir(pool->def->target.path)) == NULL) { opentries++; - if (errno == ENOENT && opentries < 50) { + if (wait && errno == ENOENT && opentries < 50) { usleep(100 * 1000); goto reopen; } @@ -1387,7 +1391,7 @@ virStorageBackendStablePath(virStoragePoolObjPtr pool, * the target directory and figure out which one points * to this device node. * - * And it might need some time till the stabe path shows + * And it might need some time till the stable path shows * up, so add timeout to retry here. */ retry: @@ -1411,7 +1415,7 @@ virStorageBackendStablePath(virStoragePoolObjPtr pool, VIR_FREE(stablepath); } - if (++retry < 100) { + if (wait && ++retry < 100) { usleep(100 * 1000); goto retry; } diff --git a/src/storage/storage_backend.h b/src/storage/storage_backend.h index a67eeb7..71935a7 100644 --- a/src/storage/storage_backend.h +++ b/src/storage/storage_backend.h @@ -130,7 +130,8 @@ virStorageBackendDetectBlockVolFormatFD(virStorageVolTargetPtr target, int fd); char *virStorageBackendStablePath(virStoragePoolObjPtr pool, - const char *devpath); + const char *devpath, + bool wait); typedef int (*virStorageBackendListVolRegexFunc)(virStoragePoolObjPtr pool, char **const groups, diff --git a/src/storage/storage_backend_disk.c b/src/storage/storage_backend_disk.c index 5d9e72f..3cd4362 100644 --- a/src/storage/storage_backend_disk.c +++ b/src/storage/storage_backend_disk.c @@ -83,7 +83,7 @@ virStorageBackendDiskMakeDataVol(virStoragePoolObjPtr pool, * dir every time its run.

[libvirt] [PATCH] put dnsmasq parameters into a file instead of the command line
by Gene Czarcinski 23 Oct '12

23 Oct '12

This patch changes the way parameters are passed to dnsmasq. They are put into a conf-file instead of being on the dnsmasq command line. This patch includes the --interface patch and has updated the related tests for the new data format, etc. **NOTE** The command line now contains --conf-file=<filename> and a new parameter --conf-dir=<directoryname> has been added. The new file and directory are put in the same directory as the leases file. --- src/network/bridge_driver.c | 245 ++++++++++++--------- src/network/bridge_driver.h | 8 +-

[libvirt] [PATCHv8 00/11] blockjob: storage migration via block-copy
by Eric Blake 22 Oct '12

22 Oct '12

v7 of these patches is here: https://www.redhat.com/archives/libvir-list/2012-September/msg01122.html Since then, I have rebased the series on top of my block-commit work, which changed (and simplified) several patches. Also, upstream qemu is closer to taking Paolo's patches that actually add the 'drive-mirror' monitor command, although it still isn't official there; so I'm still a bit reluctant to push patches 3-11 into libvirt.git until qemu.git actually gains support for block copy. Patches 1 and 2 are new, and can be applied now if they get a good review. I've done some light testing with the qemu-kvm-rhev of RHEV 3.0, so I'm fairly confident that my rebase work is correct.

[libvirt] how libvirt communicate with qemu?
by yue 22 Oct '12

22 Oct '12

i am reading source code, begin with tracing simple command line ,like virsh list and forth. please look at my qurestions 1.how libvirt communicate with qemu? call qemu'lib or open special device/socket? 2. i do not find the implement of function qemuAgentOpen---->qemuAgentInitialize(). i also search qemu-kvm source 3. qemuListAllDomains is the function which corespond to virsh-list. please explain this function . virDomainList(conn, driver->domains.objs, domains, flags); i) it seems driver->domains.objs have gotten all dmains. so when and where driver->domains.objs is assigned. ii)and what is conn,and its definition? thanks.

[libvirt] [PATCH RFC] helper of copy-storage-* features
by liguang 22 Oct '12

22 Oct '12

help to create disk images copy-storage-* required, try to do non-shared migration without bothering to create disk images at target by hand. consider this situation: 1. non-shared migration virsh migrate --copy-storage-all ... 2. migration fails 3. create disk images required qemu-img create ... 4 migration run smoothly so, try do remove step 2, 3, 4 this kind of use had been discussed before, http://www.redhat.com/archives/libvir-list/2011-December/msg00451.html maybe there're some flaws: - It did not handle more about complete situations suggested by Daniel P. Berrange, https://www.redhat.com/archives/libvir-list/2012-October/msg00407.html but may try to take care of them later. so, now only normal disk image files be handled. - for creation of disk images, size was setting as 0xffffffff boldly, hope it can consolidate qemu, haven't constructed a comfortable idea to solve it.

[libvirt] [PATCH 0/2] qemu: Check if qemu is VNC capable
by Doug Goldstein 22 Oct '12

22 Oct '12

This is the initial series where I'll be exposing the graphical support that QEMU has via capabilities but I'm breaking it up to get in as much as possible based on my available time. This initial set adds checks to see that your QEMU binary has VNC support instead of assuming that it does. A large Gentoo user apparently just uses SPICE and as a result we now provide the ability to install QEMU without VNC. While this is not a recommended configuration its certainly valid and libvirt should not assume it exists.

[libvirt] [PATCH] migrate: v2: use VIR_DOMAIN_XML_MIGRATABLE when available
by Ján Tomko 22 Oct '12

22 Oct '12

In v2 migration protocol, XML is obtained by calling domainGetXMLDesc. This includes the default USB controller in XML, which breaks migration to older libvirt (before 0.9.2). Commit 409b5f549530e7b3a33f4505f2cad2e26896107c qemu: Emit compatible XML when migrating a domain only fixed this for v3 migration. This patch uses the new VIR_DOMAIN_XML_MIGRATABLE flag (detected by VIR_DRV_FEATURE_XML_MIGRATABLE) to obtain XML without the default controller, enabling backward v2 migration. --- src/libvirt.c | 13 ++++++++++--- src/libvirt_internal.h | 5 +++++ src/qemu/qemu_driver.c | 1 + 3 files changed, 16 insertions(+), 3 deletions(-) diff --git a/src/libvirt.c b/src/libvirt.c index e3ddf27..f6f5b91 100644 --- a/src/libvirt.c +++ b/src/libvirt.c @@ -4620,6 +4620,7 @@ virDomainMigrateVersion2 (virDomainPtr domain, int cookielen = 0, ret; virDomainInfo info; virErrorPtr orig_err = NULL; + unsigned int getxml_flags = 0; int cancelled; VIR_DOMAIN_DEBUG(domain, "dconn=%p, flags=%lx, dname=%s, uri=%s, bandwidth=%lu", @@ -4646,9 +4647,15 @@ virDomainMigrateVersion2 (virDomainPtr domain, virDispatchError(domain->conn); return NULL; } - dom_xml = domain->conn->driver->domainGetXMLDesc(domain, - VIR_DOMAIN_XML_SECURE | - VIR_DOMAIN_XML_UPDATE_CPU); + + if (VIR_DRV_SUPPORTS_FEATURE(domain->conn->driver, domain->conn, + VIR_DRV_FEATURE_XML_MIGRATABLE)) { + getxml_flags |= VIR_DOMAIN_XML_MIGRATABLE; + } else { + getxml_flags |= VIR_DOMAIN_XML_SECURE | VIR_DOMAIN_XML_UPDATE_CPU; + } + + dom_xml = domain->conn->driver->domainGetXMLDesc(domain, getxml_flags); if (!dom_xml) return NULL; diff --git a/src/libvirt_internal.h b/src/libvirt_internal.h index 23e7153..71483e4 100644 --- a/src/libvirt_internal.h +++ b/src/libvirt_internal.h @@ -95,6 +95,11 @@ enum { * messages). */ VIR_DRV_FEATURE_PROGRAM_KEEPALIVE = 10, + + /* + * Support for VIR_DOMAIN_XML_MIGRATABLE flag in domainGetXMLDesc + */ + VIR_DRV_FEATURE_XML_MIGRATABLE = 11, }; diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index 76730c6..0c35dad 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -1130,6 +1130,7 @@ qemudSupportsFeature (virConnectPtr conn ATTRIBUTE_UNUSED, int feature) case VIR_DRV_FEATURE_MIGRATE_CHANGE_PROTECTION: case VIR_DRV_FEATURE_FD_PASSING: case VIR_DRV_FEATURE_TYPED_PARAM_STRING: + case VIR_DRV_FEATURE_XML_MIGRATABLE: return 1; default: return 0; -- 1.7.8.6

This fixes the problem reported in: https://bugzilla.redhat.com/show_bug.cgi?id=868389 Previously, the dnsmasq hosts file (used for static dhcp entries, and addnhosts file (used for additional dns host entries) were only created/referenced on the dnsmasq commandline if there was something to put in them at the time the network was started. Once we can update a network definition while it's active (which is now possible with virNetworkUpdate), this is no longer a valid strategy - if there were 0 dhcp static hosts (resulting in no reference to the hosts file on the commandline), then one was later added, the commandline wouldn't have linked dnsmasq up to the file, so even though we create it, dnsmasq doesn't pay any attention. The solution is to just always create these files and reference them on the dnsmasq commandline (almost always, anyway). That way dnsmasq can notice when a new entry is added at runtime (a SIGHUP is sent to dnsmasq by virNetworkUdpate whenever a host entry is added or removed) The exception to this is that the dhcp static hosts file isn't created if there are no lease ranges *and* no static hosts. This is because in this case dnsmasq won't be setup to listen for dhcp requests anyway - in that case, if the count of dhcp hosts goes from 0 to 1, dnsmasq will need to be restarted anyway (to get it listening on the dhcp port). Likewise, if the dhcp hosts count goes from 1 to 0 (and there are no dhcp ranges) we need to restart dnsmasq so that it will stop listening on port 67. These special situations are handled in the bridge driver's networkUpdate() by checking for ((bool) nranges||nhosts) both before and after the update, and triggering a dnsmasq restart if the before and after don't match. --- src/network/bridge_driver.c | 56 +++++++++++++++++++--- src/util/dnsmasq.c | 12 +++-- tests/networkxml2argvdata/isolated-network.argv | 4 +- .../nat-network-dns-srv-record-minimal.argv | 3 +- .../nat-network-dns-srv-record.argv | 3 +- .../nat-network-dns-txt-record.argv | 3 +- tests/networkxml2argvdata/nat-network.argv | 3 +- tests/networkxml2argvdata/netboot-network.argv | 5 +- .../networkxml2argvdata/netboot-proxy-network.argv | 2 + tests/networkxml2argvdata/routed-network.argv | 3 +- 10 files changed, 75 insertions(+), 19 deletions(-) diff --git a/src/network/bridge_driver.c b/src/network/bridge_driver.c index fa909a1..1c97f29 100644 --- a/src/network/bridge_driver.c +++ b/src/network/bridge_driver.c @@ -751,12 +751,19 @@ networkBuildDnsmasqArgv(virNetworkObjPtr network, if (networkBuildDnsmasqHostsfile(dctx, ipdef, network->def->dns) < 0) goto cleanup;

On F17 at least, every time libvirtd starts we get this in syslog: libvirtd: Could not find keytab file: /etc/libvirt/krb5.tab: No such file or directory This comes from cyrus-sasl, and happens regardless of whether the gssapi plugin is requested, which is what actually uses /etc/libvirt/krb5.tab.
