[libvirt] [PATCH v3] bye to close(), welcome to VIR_(FORCE_)CLOSE()
by Stefan Berger 09 Nov '10

09 Nov '10

Now that 0.8.5 is out, here is another posting of this big cleanup patch. If there are some dubious hunks in it, please let me know and I'd rather cut them out and we fix them with in separate patches... There were some problems with Eric's suggested cfg.mk extension (showing contents of error messages with 'close' as text), so I could not add the 'sc_avoid_close' to it. I again put the diff of tree+v3 against tree+v1 to the end of the patch. I forward-ported V1 for that. V3: - reaction to Daniel's comments on V2 V2: - forgot to convert close ( occurrences (with whitespace) - following Eric's and Laine's comments Using automated replacement with sed and editing I have now replaced all occurrences of close() with VIR_(FORCE_)CLOSE() except for one, of course. Some replacements were straight forward, others I needed to pay attention. I hope I payed attention in all the right places... Please have a look. This should have at least solved one more double-close error.

[libvirt] [PATCH] 0/4 Add SMBIOS settings to domain definition
by Daniel Veillard 09 Nov '10

09 Nov '10

The SMBIOS data are a standardized set of data structures available in the BIOS area of PCs. Those blocks of data describe things like BIOS version informations, machine vendor, model and identifiers, as well as various parts of the machine capability. On a linux machine running dmidecode allows to dump those informations. Spec available at the DMTF: http://dmtf.org/standards/smbios From a virtualization POV, it's mostly the first block describing the BIOS named "type 0" and the second block describing the machine named "type 1" which are of interest. Those data are usually accessed either from the OS or from management application, and being able to override the default setings may be needed for such management. The suggested XML description follows the logical structure of the data, one top smbios description, with one or more blocks, each containing the entries, the example below gives an idea: <smbios> <table type="0"> <entry name="Vendor">QEmu/KVM</entry> <entry name="Version">0.13</entry> </table> <table type="1"> <entry name="Manufacturer">Fedora</entry> <entry name="Product">Virt-Manager</entry> <entry name="Version">0.8.2-3.fc14</entry> <entry name="UUID">c7a5fdbdedaf9455926ad65c16db1809</entry> </table> </smbios> The patch serie includes: - the change to the doamin schemas - the code to parse this in config structure - the QEmu driver part - a test example Currently missing is the conf code to save the data back, and documentation for the domain extension. I think it's possible set some of those settings in Xen too, but I don't know if I will take the time of a driver for it. For ESX it seems there is an option to inherit some of the SMBIOS data from the host on the guest but I'm not sure some of the fields can be manipulated directly. I don't know what VirtualBox can set there either, Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel(a)veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/

[libvirt] [PATCH v4] qemu: call drive_del in DetachPciDiskDevice
by Ryan Harper 09 Nov '10

09 Nov '10

Currently libvirt doesn't confirm whether the guest has responded to the disk removal request. In some cases this can leave the guest with continued access to the device while the mgmt layer believes that it has been removed. With a recent qemu monitor command[1] we can deterministically revoke a guests access to the disk (on the QEMU side) to ensure no futher access is permitted. This patch adds support for the drive_del() command and introduces it in the disk removal paths. If the guest is running in a QEMU without this command we currently explicitly check for unknown command/CommandNotFound and log the issue. If QEMU supports the command we issue the drive_del command after we attempt to remove the device. The guest may respond and remove the block device before we get to attempt to call drive_del. In that case, we explicitly check for 'Device not found' from the monitor indicating that the target drive was auto-deleted upon guest responds to the device removal notification. 1. http://thread.gmane.org/gmane.comp.emulators.qemu/84255 Signed-off-by: Ryan Harper <ryanh(a)us.ibm.com> --- Changes since v3: - Renamed DriveUnplug -> DriveDel, use drive_del monitor cmd. - Moved invocation to after DelDevice and guest notification. - Handle the case where drive is auto-deleted before we call DriveDel by catching and ignoring 'Device not found' error. - Simplified DriveDel invocation; no need to check return codes as the monitor implementations handle all failure case and logs or ignores as needed. Changes since v2: - use VIR_ERROR to report when unplug command not found Changes since v1: - return > 0 when command isn't present, < 0 on command failure - detect when drive_unplug command isn't present and log error instead of failing entire command src/qemu/qemu_driver.c | 29 ++++++++++++++++++++++ src/qemu/qemu_monitor.c | 19 ++++++++++++++ src/qemu/qemu_monitor.h | 3 ++ src/qemu/qemu_monitor_json.c | 38 +++++++++++++++++++++++++++++ src/qemu/qemu_monitor_json.h | 3 ++ src/qemu/qemu_monitor_text.c | 54 ++++++++++++++++++++++++++++++++++++++++++ src/qemu/qemu_monitor_text.h | 3 ++ 7 files changed, 149 insertions(+), 0 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index e7b37e1..d01bb2c 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -9037,6 +9037,7 @@ static int qemudDomainDetachPciDiskDevice(struct qemud_driver *driver, virDomainDiskDefPtr detach = NULL; qemuDomainObjPrivatePtr priv = vm->privateData; virCgroupPtr cgroup = NULL; + char drivestr[PATH_MAX]; i = qemudFindDisk(vm->def, dev->data.disk->dst); @@ -9077,6 +9078,20 @@ static int qemudDomainDetachPciDiskDevice(struct qemud_driver *driver, goto cleanup; } } + + /* build the actual drive id string as the disk->info.alias doesn't + * contain the QEMU_DRIVE_HOST_PREFIX that is passed to qemu */ + if ((ret = snprintf(drivestr, sizeof(drivestr), "%s%s", + QEMU_DRIVE_HOST_PREFIX, + detach->info.alias)) + < 0 || ret >= sizeof(drivestr)) { + virReportOOMError(); + goto cleanup; + } + + /* disconnect guest from host device */ + qemuMonitorDriveDel(priv->mon, drivestr); + qemuDomainObjExitMonitorWithDriver(driver, vm); qemuDomainDiskAudit(vm, detach, NULL, "detach", ret >= 0); @@ -9116,6 +9131,7 @@ static int qemudDomainDetachSCSIDiskDevice(struct qemud_driver *driver, virDomainDiskDefPtr detach = NULL; qemuDomainObjPrivatePtr priv = vm->privateData; virCgroupPtr cgroup = NULL; + char drivestr[PATH_MAX]; i = qemudFindDisk(vm->def, dev->data.disk->dst); @@ -9147,6 +9163,19 @@ static int qemudDomainDetachSCSIDiskDevice(struct qemud_driver *driver, qemuDomainObjExitMonitor(vm); goto cleanup; } + + /* build the actual drive id string as the disk->info.alias doesn't + * contain the QEMU_DRIVE_HOST_PREFIX that is passed to qemu */ + if ((ret = snprintf(drivestr, sizeof(drivestr), "%s%s", + QEMU_DRIVE_HOST_PREFIX, + detach->info.alias)) + < 0 || ret >= sizeof(drivestr)) { + virReportOOMError(); + goto cleanup; + } + /* disconnect guest from host device */ + qemuMonitorDriveDel(priv->mon, drivestr); + qemuDomainObjExitMonitorWithDriver(driver, vm); qemuDomainDiskAudit(vm, detach, NULL, "detach", ret >= 0); diff --git a/src/qemu/qemu_monitor.c b/src/qemu/qemu_monitor.c index 2366fdb..80adba4 100644 --- a/src/qemu/qemu_monitor.c +++ b/src/qemu/qemu_monitor.c @@ -1781,6 +1781,25 @@ int qemuMonitorGetAllPCIAddresses(qemuMonitorPtr mon, return ret; } +int qemuMonitorDriveDel(qemuMonitorPtr mon, + const char *drivestr) +{ + DEBUG("mon=%p drivestr=%s", mon, drivestr); + int ret; + + if (!mon) { + qemuReportError(VIR_ERR_INVALID_ARG, "%s", + _("monitor must not be NULL")); + return -1; + } + + if (mon->json) + ret = qemuMonitorJSONDriveDel(mon, drivestr); + else + ret = qemuMonitorTextDriveDel(mon, drivestr); + return ret; +} + int qemuMonitorDelDevice(qemuMonitorPtr mon, const char *devalias) { diff --git a/src/qemu/qemu_monitor.h b/src/qemu/qemu_monitor.h index 7d09145..8cda43b 100644 --- a/src/qemu/qemu_monitor.h +++ b/src/qemu/qemu_monitor.h @@ -381,6 +381,9 @@ int qemuMonitorDelDevice(qemuMonitorPtr mon, int qemuMonitorAddDrive(qemuMonitorPtr mon, const char *drivestr); +int qemuMonitorDriveDel(qemuMonitorPtr mon, + const char *drivestr); + int qemuMonitorSetDrivePassphrase(qemuMonitorPtr mon, const char *alias, const char *passphrase); diff --git a/src/qemu/qemu_monitor_json.c b/src/qemu/qemu_monitor_json.c index d2c6f0a..a380ab2 100644 --- a/src/qemu/qemu_monitor_json.c +++ b/src/qemu/qemu_monitor_json.c @@ -2244,6 +2244,44 @@ int qemuMonitorJSONAddDrive(qemuMonitorPtr mon, } +int qemuMonitorJSONDriveDel(qemuMonitorPtr mon, + const char *drivestr) +{ + int ret; + virJSONValuePtr cmd; + virJSONValuePtr reply = NULL; + + DEBUG("JSONDriveDel drivestr=%s", drivestr); + cmd = qemuMonitorJSONMakeCommand("drive_del", + "s:id", drivestr, + NULL); + if (!cmd) + return -1; + + ret = qemuMonitorJSONCommand(mon, cmd, &reply); + + if (ret == 0) { + /* See if drive_del isn't supported */ + if (qemuMonitorJSONHasError(reply, "CommandNotFound")) { + VIR_ERROR0(_("deleting disk is not supported.

[libvirt] [PATCH 0/9] Core support for SPICE configuration (v2)
by Daniel P. Berrange 09 Nov '10

09 Nov '10

A version 2 of http://www.redhat.com/archives/libvir-list/2010-November/msg00049.html This wires up the core support for SPICE configuration and QXL graphics devices. It also introduces a syntax for setting password expiry times for VNC/SPICE servers, although this isn't yet supported in upstream QEMU. Also not yet included here is seemless migration of SPICE clients, which is also pending QEMU work. The main changes in v2 are adding docs and fixing the minor issues that Eric found. Daniel
