[libvirt] [RFC: PATCH 0/2] Display allocation during dumpxml
by Eric Blake 18 Nov '14

18 Nov '14

I'm still working on code to populate the latest numbers for each disk of a domain, including getting numbers for offline domains, but have confirmed that with these two patches alone I'm able to see <capacity> and <allocation> numbers for block volumes of live domains (thanks to how we populate backing chain information). So while there are more patches to come, I'd like to get review started on my proposed API addition.

[libvirt] [PATCH v2 0/4] use the 'vram' attribute for QEMU video devices
by Pavel Hrdina 18 Nov '14

18 Nov '14

There are some changes from the first version. We will not have a new 'vgamem' attribute for video devices because we can use the 'vram' attribute. So far for QEMU the 'vram' is used only to set the secondary ram for QXL which seems to be correct as the secondary ram is used for pixmaps and surfaces. The 'vgamem_mb' parameter for QXL sets the VGA framebuffer size, but the VGA mode in QXL is used only as fallback if the OS doesn't have any QXL drivers or before the drivers are loaded. The VGA framebuffer is part of the first ram for QXL and for that we have 'ram' attribute. The rest of the first ram is memory for rendering commands and it's data. Default VGA framebuffer size is 8MB which is sufficient. Other QEMU video devices have only 'vgamem_mb' parameter and we will use the 'vram' attribute to set the size of video memory as it's used also for other hypervisors. The first two patches clean the usage of vram attribute and improve the documentation and the rest two patches implements usage of 'vram' attribute for remaining QEMU video devices.

[libvirt] How can I get drive_mirror migration progress with non-shared storage on KVM ?
by Wang Rui 18 Nov '14

18 Nov '14

Hi, I want to get a total progress(memory + storage). In none drive mirror migration, I can use virDomainGetJobInfo API to get the total progress. But in drive mirror migration, it seems that I must get file progress by virDomainGetBlockJobInfo and momery progress by virDomainGetJobInfo separately. So does the job status. Is there a way to get the total progress and job status? Thanks.

[libvirt] [PATCH v3] leaseshelper: improvements to support all events
by Nehal J Wani 17 Nov '14

17 Nov '14

This patch enables the helper program to detect event(s) triggered when there is a change in lease length or expiry and client-id. This transfers complete control of leases database to libvirt and obsoletes use of the lease database file (<network-name>.leases). That file will not be created, read, or written. This is achieved by adding the option --leasefile-ro to dnsmasq and passing a custom env var to leaseshelper, which helps us map events related to leases with their corresponding network bridges, no matter what the event be. Also, this requires the addition of a new non-lease entry in our custom lease database: "server-duid". It is required to identify a DHCPv6 server. Now that dnsmasq doesn't maintain its own leases database, it relies on our helper program to tell it about previous leases and server duid. Thus, this patch makes our leases program honor an extra action: "init", in which it sends the known info in a particular format to dnsmasq by printing it to stdout. --- This is compatible with libvirt 1.2.6 as only additions have been introduced, and the old leases file (*.status) will still be supported. v3: * Add server-duid as an entry in the lease object for every ipv6 lease. * Remove unnecessary variables and double copies. * Take value from DNSMASQ_OLD_HOSTNAME if hostname is not known. v2: http://www.redhat.com/archives/libvir-list/2014-July/msg01109.html v1: https://www.redhat.com/archives/libvir-list/2014-July/msg00568.html src/network/bridge_driver.c | 3 + src/network/leaseshelper.c | 132 +++++++++++++++++++++++++++++++++++--------- 2 files changed, 109 insertions(+), 26 deletions(-) diff --git a/src/network/bridge_driver.c b/src/network/bridge_driver.c index 965fdec..b578b3a 100644 --- a/src/network/bridge_driver.c +++ b/src/network/bridge_driver.c @@ -1288,7 +1288,10 @@ networkBuildDhcpDaemonCommandLine(virNetworkObjPtr network, cmd = virCommandNew(dnsmasqCapsGetBinaryPath(caps)); virCommandAddArgFormat(cmd, "--conf-file=%s", configfile); + /* Libvirt gains full control of leases database */ + virCommandAddArgFormat(cmd, "--leasefile-ro"); virCommandAddArgFormat(cmd, "--dhcp-script=%s", leaseshelper_path); + virCommandAddEnvPair(cmd, "VIR_BRIDGE_NAME", network->def->bridge); *cmdout = cmd; ret = 0; diff --git a/src/network/leaseshelper.c b/src/network/leaseshelper.c index c8543a2..e984cbb 100644 --- a/src/network/leaseshelper.c +++ b/src/network/leaseshelper.c @@ -50,6 +50,12 @@ */ #define VIR_NETWORK_DHCP_LEASE_FILE_SIZE_MAX (32 * 1024 * 1024) +/* + * Use this when passing possibly-NULL strings to printf-a-likes. + * Required for unknown parameters during init call. + */ +#define EMPTY_STR(s) ((s) ?

[libvirt] [PATCH] drvbhyve: Use boot-order for grub-bhyve boot device
by Conrad Meyer 14 Nov '14

14 Nov '14

Rather than just picking the first CD (or failing that, HDD) we come across, if the user has picked a boot device ordering with <boot order=''>, respect that (and just try to boot the lowest-index device). Adds two sets of tests to bhyve2xmlargv; 'grub-bootorder' shows that we pick a user-specified device over the first device in the domain; 'grub-bootorder2' shows that we pick the first (lowest index) device. --- This is a follow-up to the 'Add non-FreeBSD guest support to Bhyve driver' patch series to fix the grub-bhyve automagic configuration to respect <boot order=''> in the domain.

[libvirt] [PATCH 0/3] libxl migration improvements
by Jim Fehlig 14 Nov '14

14 Nov '14

This series of patches fixes problems discovered in libxl migration. The first patch fixes an issue that went undetected while testing the initial implementation of migration. Receiving migration data occurs in the context of an event loop callback, effectively blocking the event loop during the entire migration process. The patch moves the work of receiving migration data to a thread. Interestingly, this issue manifested in a failed migration due to failed keepalives, which would kill virsh's connection to dst host. The dst host failed to respond to keepalives since its event loop was blocked on receiving migration data. Ultimately the migration perform phase would succeed leaving a running domain on dst. However, the subsequent finish phase would fail since virsh's connection to dst had been killed by the keepalive failure. Since finish failed, the confirm phase would resume the domain on src. Yikes! Same domain running on two different hosts :(. Patches 2 and 3 improve handling of errors in the event the perform or finish phases of migration fail. See the individual patches for details.

Since QEMU 1.2.0, we switched to QMP probing instead of parsing -help (and other commands, such as -cpu ?) output. However, if QMP probing failed, we still tried starting QEMU with various options and parsing the output, which was guaranteed to fail because the output changed. Let's just refuse parsing -help for QEMU >= 1.2.0. https://bugzilla.redhat.com/show_bug.cgi?id=1160318 Signed-off-by: Jiri Denemark <jdenemar(a)redhat.com> --- Notes: Version 2: - fixes comparison to

[libvirt] [PATCH v2] qemu: add port check for host when disk type is network
by Shanzhi Yu 13 Nov '14

[libvirt] [nova] - 'nova reboot' causes console-log truncated
by Surojit Pathak 13 Nov '14

13 Nov '14

Hi all, [Issue observed] If we issue 'nova reboot <server>', we get to have the console output of the latest bootup of the server only. The console output of the previous boot for the same server vanishes due to truncation[1]. If we do reboot from within the VM instance [ #sudo reboot ], or reboot the instance with 'virsh reboot <instance>' the behavior is not the same, where the console.log keeps increasing, with the new output being appended. This loss of history makes some debugging scenario difficult due to lack of information being available. Please point me to any solution/blueprint for this issue, if already planned. Otherwise, please comment on my analysis and proposals as solution, below - [Analysis] Nova's libvirt driver on compute node tries to do a graceful restart of the server instance, by attempting a soft_reboot first. If soft_reboot fails, it attempts a hard_reboot. As part of soft_reboot, it brings down the instance by calling shutdown(), and then calls createWithFlags() to bring this up. Because of this, qemu-kvm process for the instance gets terminated and new process is launched. In QEMU, the chardev file is opened with O_TRUNC, and thus we lose the previous content of the console.log file. On the other-hand, during 'virsh reboot <instance>', the same qemu-kvm process continues, and libvirt actually does a qemuDomainSetFakeReboot(). Thus the same file continues capturing the new console output as a continuation into the same file. [Proposals for solution] 1. NOVA, driven by certain configuration, will backup the console file, before creating the domain, during reboot scenario. viz. doing a backup of console.log as console.log.0. How many such backups of log-file to keep, what can be the maximum size of the file, 'logrotate` to be used or not - all these can come to NOVA as configuration parameter. Pros - As NOVA libvirt driver is not using libvirt's reboot() functionality knowingly, this problem can be better addressed from the same layer. Cons - NOVA's libvirt layer building awareness of the console files is not clean from modularity. 2. virDomainCreateWithFlags() will have a new flag value to indicate logs to be appended instead of truncated, if FILE option is used. This config will be passed to QEMU, while spawning the process. - Changes will be not in OpenStack Code, but in libvirt and QEMU. Cons - We may have to do the similar implementation for all the drivers of libvirt. Pros - This feature's use-case is there in case of 'virsh shutdown <instance>', followed by a 'virsh start <instance>' too.

[libvirt] [PATCH] qemu: Don't try to parse -help for new QEMU
by Jiri Denemark 13 Nov '14

13 Nov '14

Since QEMU 1.2.0, we switched to QMP probing instead of parsing -help (and other commands, such as -cpu ?) output. However, if QMP probing failed, we still tried starting QEMU with various options and parsing the output, which was guaranteed to fail because the output changed. Let's just refuse parsing -help for QEMU >= 1.2.0. https://bugzilla.redhat.com/show_bug.cgi?id=1160318 Signed-off-by: Jiri Denemark <jdenemar(a)redhat.com> --- src/qemu/qemu_capabilities.c | 10 ++++++++++ 1 file changed, 10 insertions(+) diff --git a/src/qemu/qemu_capabilities.c b/src/qemu/qemu_capabilities.c index 74a3b24..bef96d5 100644 --- a/src/qemu/qemu_capabilities.c +++ b/src/qemu/qemu_capabilities.c @@ -1384,6 +1384,16 @@ int virQEMUCapsParseHelpStr(const char *qemu, *version = (major * 1000 * 1000) + (minor * 1000) + micro; + /* Refuse to parse -help output for QEMU releases >= 1.2.0 that should be + * using QMP probing. + */ + if (*version > 1002000) { + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, + _("QEMU %u.%u.%u is too new for help parsing"), + major, minor, micro); + goto cleanup; + } + if (virQEMUCapsComputeCmdFlags(help, *version, *is_kvm, *kvm_version, qemuCaps, check_yajl) < 0) goto cleanup; -- 2.1.3

[libvirt] [PATCH] qemu: Always set migration capabilities
by Jiri Denemark 13 Nov '14

13 Nov '14

We used to set migration capabilities only when a user asked for them in flags. This is fine when migration succeeds since the QEMU process is killed in the end but in case migration fails or if it's cancelled, some capabilities may remain turned on with no way to turn them off. To fix that, migration capabilities have to be turned on if requested but explicitly turned off in case they were not requested but QEMU supports them. https://bugzilla.redhat.com/show_bug.cgi?id=1160997 Signed-off-by: Jiri Denemark <jdenemar(a)redhat.com> --- src/qemu/qemu_migration.c | 42 +++++++++++++++++++++++++++++------------- src/qemu/qemu_monitor.c | 5 +++-- src/qemu/qemu_monitor.h | 3 ++- src/qemu/qemu_monitor_json.c | 5 +++-- src/qemu/qemu_monitor_json.h | 3 ++- tests/qemumonitorjsontest.c | 3 ++- 6 files changed, 41 insertions(+), 20 deletions(-) diff --git a/src/qemu/qemu_migration.c b/src/qemu/qemu_migration.c index c797206..ff692a5 100644 --- a/src/qemu/qemu_migration.c +++ b/src/qemu/qemu_migration.c @@ -1804,6 +1804,7 @@ qemuMigrationSetOffline(virQEMUDriverPtr driver, static int qemuMigrationSetCompression(virQEMUDriverPtr driver, virDomainObjPtr vm, + bool state, qemuDomainAsyncJob job) { qemuDomainObjPrivatePtr priv = vm->privateData;

[libvirt] [PATCH] virsh: Fix msg: blockjob is aborted from another client
by Erik Skultety 13 Nov '14

13 Nov '14

When a block{pull, copy, commit} is aborted via keyboard interrupt, the job is properly canceled followed by proper error message. However, when the job receives an abort from another client connected to the same domain, the error message incorrectly indicates that a blockjob has been finished successfully, though the abort request took effect. This patch introduces a new blockjob abort handler, which is registered when the client calls block{copy,commit,pull} routine, providing its caller the status of the finished blockjob. --- tools/virsh-domain.c | 74 +++++++++++++++++++++++++++++++++++++++++++++++++--- 1 file changed, 71 insertions(+), 3 deletions(-) diff --git a/tools/virsh-domain.c b/tools/virsh-domain.c index 8e743f1..025395f 100644 --- a/tools/virsh-domain.c +++ b/tools/virsh-domain.c @@ -1710,6 +1710,17 @@ static void vshCatchInt(int sig ATTRIBUTE_UNUSED, intCaught = 1; } +static void +vshBlockJobStatusHandler(virConnectPtr conn ATTRIBUTE_UNUSED, + virDomainPtr dom ATTRIBUTE_UNUSED, + const char *disk ATTRIBUTE_UNUSED, + int type ATTRIBUTE_UNUSED, + int status, + void *opaque) +{ + *(int *) opaque = status; +} + /* * "blockcommit" command */ @@ -1809,6 +1820,8 @@ cmdBlockCommit(vshControl *ctl, const vshCmd *cmd) const char *path = NULL; bool quit = false; int abort_flags = 0; + int status = -1; + int cb_id = -1; blocking |= vshCommandOptBool(cmd, "timeout") || pivot || finish; if (blocking) { @@ -1838,6 +1851,18 @@ cmdBlockCommit(vshControl *ctl, const vshCmd *cmd) return false; } + virConnectDomainEventGenericCallback cb = + VIR_DOMAIN_EVENT_CALLBACK(vshBlockJobStatusHandler); + + if ((cb_id = virConnectDomainEventRegisterAny(ctl->conn, + dom, + VIR_DOMAIN_EVENT_ID_BLOCK_JOB_2, + cb, + &status, + NULL)) < 0) { + goto cleanup; + } + if (!blockJobImpl(ctl, cmd, VSH_CMD_BLOCK_JOB_COMMIT, &dom)) goto cleanup; @@ -1879,7 +1904,7 @@ cmdBlockCommit(vshControl *ctl, const vshCmd *cmd) intCaught ?
