[libvirt] [PATCH 0/4] Make uninstall clean again
by Michal Privoznik 20 Apr '16

20 Apr '16

It's been a while since 'make uninstall' cleaned up everything that 'make install' created. I've noticed this while trying to figure out why some build test on *BSD is failing (fix for that is in the first patch btw).

[libvirt] [PATCH v2 1/2] Explicitly error on uri=qemu://system

It's a fairly common error that a user tries to connect to a URI like qemu://system or qemu://session (missing a slash). This errors like: $ virsh --connect qemu://session error: failed to connect to the hypervisor error: Unable to resolve address 'session' service '16514': No address associated with hostname If you already know that the standard qemu URI has 3 slashes, that error will make it obvious enough.

[libvirt] [PATCH] Revert "daemon: use socket activation with systemd"
by Cole Robinson 20 Apr '16

20 Apr '16

This reverts commit 1e9808d3a1e00a7121bae8b163d9c42d441d2ca8. We shouldn't advertise libvirtd.socket activation, since currently it means VM/network/... autostart won't work as expected. We tried to find a middle ground by installing the config file without an [Install] section, since systemd won't allow .socket to be enabled without one... or at least it did do that; presently on f24 it allows activating the socket quite happily. This also caused user confusion[1] Just remove the socket file. I've filed a new RFE to track coming up with a solution to the autostart problem[2], we can point users at that if there's more confusion: [1]: https://bugzilla.redhat.com/show_bug.cgi?id=1279348 [2]: https://bugzilla.redhat.com/show_bug.cgi?id=1326136 --- .gitignore | 1 - daemon/Makefile.am | 14 ++------------ daemon/libvirtd.conf | 5 ----- daemon/libvirtd.service.in | 5 +++++ daemon/libvirtd.socket.in | 11 ----------- libvirt.spec.in | 7 ++----- 6 files changed, 9 insertions(+), 34 deletions(-) delete mode 100644 daemon/libvirtd.socket.in diff --git a/.gitignore b/.gitignore index 0d12c5c..381db69 100644 --- a/.gitignore +++ b/.gitignore @@ -63,7 +63,6 @@ /daemon/libvirtd.pod /daemon/libvirtd.policy /daemon/libvirtd.service -/daemon/libvirtd.socket /daemon/test_libvirtd.aug /docs/aclperms.htmlinc /docs/apibuild.py.stamp diff --git a/daemon/Makefile.am b/daemon/Makefile.am index 2dbe81b..fc6fd95 100644 --- a/daemon/Makefile.am +++ b/daemon/Makefile.am @@ -59,7 +59,6 @@ EXTRA_DIST = \ libvirt.rules \ libvirtd.sasl \ libvirtd.service.in \ - libvirtd.socket.in \ libvirtd.sysconf \ libvirtd.sysctl \ libvirtd.aug \ @@ -446,18 +445,15 @@ endif !

[libvirt] [PATCH REBASE 0/4] vz: use disk bus and target name as disk id
by Nikolay Shirokovskiy 20 Apr '16

20 Apr '16

This series is a preparation to implement device update functionality. In case of disk updates disk bus and disk target name pair is considered disk id. We already have places in vz driver code where we use disk source as id. These places are either not critical (see boot patch) or correct (see detach patch) so we need not to fix them immediately to use more rubust id. But as this id will be introduced anyway for disk updates let's move to new id in existing code. This way we have single id for disks.

[libvirt] [PATCH 00/10] Convert secret driver to use hashed object

20 Apr '16

This series replaces the usage of linked list in secret driver with a hashed object list as was suggested in the review in the last patch of the previous secret driver changes series: http://www.redhat.com/archives/libvir-list/2016-February/msg01274.html Patch 1 - starts the ball rolling Patch 2 - is yet another code optimization (as found in bridge_driver) Patches 3-8 - Add the new API's "slowly" (for review purposes) Patch 9 - replaces the usage of linked lists with the hashed object Patch 10 - moves the secretLoadAllConfigs to secret_conf The changes are loosely modeled after both virdomainobj and network_conf functionality. The real meat and potato(e)s is found in patches 5 and 9. Other functions should be relatively straightforward. I've done testing of various virsh secret-* commands (both valid and invalid options) as well as performing driver start, stop, and reload testing. Each patch was built using 'check' and 'syntax-check'. The end result is much more code in secret_conf and much less in secret_driver.

[libvirt] [PATCH] Explicitly error on uri=qemu://system
by Cole Robinson 19 Apr '16

19 Apr '16

It's a fairly common error that a user tries to connect to a URI like qemu://system or qemu://session (missing a slash). This errors like: $ virsh --connect qemu://session error: failed to connect to the hypervisor error: Unable to resolve address 'session' service '16514': No address associated with hostname If you already know that the standard qemu URI has 3 slashes, that error will make it obvious enough. But new user's may not get it.

[libvirt] RFC: Drop unmaintained hv drivers? (phyp, xenapi, hyperv)
by Cole Robinson 19 Apr '16

19 Apr '16

Hi all, There's a few old hypervisor drivers in the tree that haven't been actively maintained for a long time. I'm curious if anyone knows of these drivers being actively used. If not I think we should consider dropping them src/phyp/ : for power VM hypervisor. Added in July 2009. The last commit that looks like it wasn't either internal API conversion, or caught by code analysis, is: commit 41461ff7f7d6ee6679aae2a8004e305c5830c9e8 Author: Eduardo Otubo <otubo(a)linux.vnet.ibm.com> Date: Tue Apr 19 12:34:08 2011 -0300 PHYP: Adding reboot domain function Adding reboot <domain> function for pHyp driver. Nearly 5 years ago. Eduardo is the primary driver author too (CCd at his email from github). Searching the upstream bug tracker for all bugs with 'phyp', the only one that's actually about the phyp driver is a report from 2 years ago that it crashes trying to open a connection: https://bugzilla.redhat.com/show_bug.cgi?id=1093094 src/xenapi/: Connecting to a xen api server. Added in March 2010. Largely appears to be a code drop, the original author/committer has never had another commit. The last xenapi specific commit seems to be: commit 484460ec4678a264c5e7355495c2f0da72cb42bd Author: Matthias Bolte <matthias.bolte(a)googlemail.com> Date: Thu Jul 21 15:16:11 2011 +0200 xenapi: Improve error reporting in xenapiOpen once again Nearly 5 years ago. The only upstream bug that was filed about xenapi is: https://bugzilla.redhat.com/show_bug.cgi?id=711372 Which was about a connection failure that was eventually fixed upstream, and dovetailed into the above referenced commit. Current xen guys, you know of anyone using this? src/hyperv/: Added in July 2011. This was largely a code drop as well; committed and patched a few times by Matthias but it was a university project by someone else. Last hyperv targeted patch was: commit 9e9ea3ead9825bd1dc2c17cea4abc8c4165591d0 Author: Matthias Bolte <matthias.bolte(a)googlemail.com> Date: Sun Sep 9 17:39:40 2012 +0200 hyperv: Fix and improve hypervListAllDomains The driver is fairly minimal as well: it can only list existing VMs and perform lifecycle operations. It can't create new VMs, and doesn't list VM device config AFAICT. Also, in general, I've never heard about anyone _actually_ using any of those drivers in the wild. There's reports here and there but it mostly sounds like people trying them out. Just an anecdote so take it with a grain of salt - Cole

[libvirt] [PATCH] network: Add support for dhcp-range lease time in the network XML configuration format and dnsmasq
by Alberto Ruiz 19 Apr '16

19 Apr '16

Hello, I've been asked to send this patch to the list for review which I originally posted at rhbz#913446 [0]. My main motivation is to be able to set a saner default for dhcp leases in Boxes for development machines where the instant volatility of the dhcp lease makes it impossible to reliably work with services after the machines have to be rebooted. One has to discover the ip again... setup ssh keys... This patch is a first attempt so feel free to let me know if I'm aiming at the right direction. Thanks!

As you know, libvirt takes advantage of xml and generate corresponding qemu command line. But how does this command line executed? Does it executed in bash shell? Or any other api is used to create the qemu process? Thank you.

[libvirt] [libvirt-php PATCH 00/29] Add PHP7 support and unit tests V2
by Neal Gompa 19 Apr '16

19 Apr '16

This patch set is a revision of the first version, taking into account some of the feedback from Michal Privoznik. I've done some patch surgery to rebase the patch set on the current git HEAD, so it should cleanly apply as-is. Additionally, I've squashed a few commits (mainly some of Remi's patches that were squashable that should be squashed). This means that Vasiliy's patches are no longer unnecessarily part of this patch set. I've updated my patches for the instructions on the php extension build system method to correct a typo on how to run the tests (`make test` instead of `make tests`) and removed the "-dev" suffix that Remi attached to the version string in libvirt-php.h, as I expect that there will likely be a libvirt-php release after this patch set is merged. I would greatly appreciate a quick review and merge of this patch set. Chuck Roydhouse (1): add arginfo for libvirt_domain_block_commit and libvirt_domain_block_job_info Frederic Mora (1): Add more tests Neal Gompa (2): Commit short instructions to using the php extension build method Bump version to 0.5.2 Remi Collet (25): add config.m4 to allow standard PHP extension build system include config.h earlier add missing arginfo adapt RETURN_STRING work on zpp register + fetch resources + hash adapt add_assoc_string_ex clean ALLOC_INIT_ZVAL zend_hash_update add_next_index_string buildable with PHP 7 bump version 0.5.2-dev fix missed (hidden) zpp calls fix PHP 5 compat fix libvirt_version + add test port test-connect.phpt to real phpt Switch all add_assoc_string_ex to add_assoc_string to avoid nul char management Fix max_connections management add test-conn-limit.phpt (as real phpt) add test-connect-get-emulator.phpt fix parse_array + build warnings convert test-install.phpt to real phpt convert test-domain-create-and-coredump.phpt to real phpt convert test-domain-create-and-get-xpath.phpt to real phpt fix PHP 5 compat again (nested macro issue) INSTALL.PHPEXT | 14 + configure.ac | 2 +- src/config.m4 | 52 + src/libvirt-php.c | 1796 ++++++++++++++++------- src/libvirt-php.h | 48 +- src/tests/example-no-disk-and-media.xml | 41 + src/tests/qemu-no-disk-and-media.xml | 41 + src/tests/skipif.inc | 3 + src/tests/test-conn-limit.phpt | 49 + src/tests/test-connect-get-capabilities.phpt | 27 + src/tests/test-connect-get-emulator.phpt | 15 + src/tests/test-connect-get-info.phpt | 110 ++ src/tests/test-connect-get-machine-types.phpt | 30 + src/tests/test-connect.phpt | 15 + src/tests/test-domain-create-and-coredump.phpt | 49 + src/tests/test-domain-create-and-get-xpath.phpt | 56 + src/tests/test-domain-create-and-shutdown.phpt | 38 + src/tests/test-domain-define.phpt | 38 + src/tests/test-domain-disk.phpt | 71 + src/tests/test-domain-get.phpt | 91 ++ src/tests/test-domain-lookup-by-name.phpt | 35 + src/tests/test-domain-nic.phpt | 52 + src/tests/test-install.phpt | 136 ++ src/tests/test-libvirt-php.img | 0 src/tests/test-logfile.phpt | 43 + src/tests/test-version-get.phpt | 27 + 26 files changed, 2330 insertions(+), 549 deletions(-) create mode 100644 INSTALL.PHPEXT create mode 100644 src/config.m4 create mode 100644 src/tests/example-no-disk-and-media.xml create mode 100644 src/tests/qemu-no-disk-and-media.xml create mode 100644 src/tests/skipif.inc create mode 100644 src/tests/test-conn-limit.phpt create mode 100644 src/tests/test-connect-get-capabilities.phpt create mode 100644 src/tests/test-connect-get-emulator.phpt create mode 100644 src/tests/test-connect-get-info.phpt create mode 100644 src/tests/test-connect-get-machine-types.phpt create mode 100644 src/tests/test-connect.phpt create mode 100644 src/tests/test-domain-create-and-coredump.phpt create mode 100644 src/tests/test-domain-create-and-get-xpath.phpt create mode 100644 src/tests/test-domain-create-and-shutdown.phpt create mode 100644 src/tests/test-domain-define.phpt create mode 100644 src/tests/test-domain-disk.phpt create mode 100644 src/tests/test-domain-get.phpt create mode 100644 src/tests/test-domain-lookup-by-name.phpt create mode 100644 src/tests/test-domain-nic.phpt create mode 100644 src/tests/test-install.phpt create mode 100644 src/tests/test-libvirt-php.img create mode 100644 src/tests/test-logfile.phpt create mode 100644 src/tests/test-version-get.phpt -- 2.5.5

When creating the master key, we used mode 0600 (which we should) but because we were creating it as root, the file is not readable by any qemu running as non-root. Fortunately, it's just a matter of labelling the file. We are generating the file path few times already, so let's label it in the same function that has access to the path already.

[libvirt] [PATCH v4 00/11] Introduce worker tuning APIs
by Erik Skultety 18 Apr '16

18 Apr '16

since v3: - fixed some indentation problem in 10/11 - for some reason daemon-side APIs did not follow our function signature conventions, e.g. if the function name starts with virAdmServer (adminServer for server-side version), it means that first argument is going to be virAdmServerPtr (virNetServerPtr for server side), etc., but for some reason, I named the server-side version adminDaemon, while passing virNetServerPtr as the first argument - fixed a bug when setting parameters would return error stating that minWorkers cannot be larger than maxWorkers for configuration: maxWorkers = 14 and minWorkers = 13 - replaced srv-workertune command with two commands srv-threadpool-info and srv-threadpool-set, since it's much easier to extend the set of options for each command separately than to do some black magic to determine which options make the command behave as a getter and which ones make it behave as a setter since v2: - all getters are now protected by threadpool mutex to prevent torn reads in concurrent execution - some checks in adminDispatchServerGetThreadpoolParameters were redundant, thus were optimizes out - fixed memory leak in adminDispatchServerGetThreadpoolParameters when allocating a newlist although typed params serialization already does that - fixed some cosmetic issues like exporting a function prototype one patch earlier than it should actually be introduced - a mistake that got there by interactive rebase Erik Skultety (11): po: Fix record ordering in POTFILES.in libvirt-host: Move virTypedParam* to libvirt-common admin: Enable usage of typed parameters util: Refactor thread creation by introducing virThreadPoolExpand util: Report system error when virThreadCreateFull fails util: Use a mutex when retrieving threadpool data util: Add more getters to threadpool parameters admin: Prepare admin protocol for future worker related procedures admin: Introduce virAdmServerGethreadPoolParameters admin: Introduce virAdmServerSetThreadPoolParameters virt-admin: Introduce srv-threadpool-info and srv-threadpool-set commands cfg.mk | 2 +- daemon/admin.c | 88 +++++++++++++ daemon/admin_server.c | 110 ++++++++++++++++ daemon/admin_server.h | 11 ++ include/libvirt/libvirt-admin.h | 71 +++++++++++ include/libvirt/libvirt-common.h.in | 185 +++++++++++++++++++++++++++ include/libvirt/libvirt-host.h | 186 ---------------------------- po/POTFILES.in | 4 +- src/admin/admin_protocol.x | 54 +++++++- src/admin/admin_remote.c | 77 ++++++++++++ src/admin_protocol-structs | 45 +++++++ src/libvirt-admin.c | 83 +++++++++++++ src/libvirt_admin_private.syms | 3 + src/libvirt_admin_public.syms | 2 + src/libvirt_private.syms | 4 + src/rpc/virnetserver.c | 37 ++++++ src/rpc/virnetserver.h | 13 ++ src/util/virthreadpool.c | 241 ++++++++++++++++++++++++++---------- src/util/virthreadpool.h | 8 ++ tools/virt-admin.c | 185 +++++++++++++++++++++++++++ 20 files changed, 1152 insertions(+), 257 deletions(-) -- 2.4.11

[libvirt] [PATCH] Libvirt: virTypedParamsValidate: Fix detection of multiple parameters
by Jason J. Herne 18 Apr '16

18 Apr '16

virTypedParamsValidate currently uses an index based check to find duplicate parameters. This check does not work. Consider the following simple example: We have only 2 keys A (multiples allowed) B (multiples NOT allowed) We are given the following list of parameters to check: A A B If you work through the validation loop you will see that our last iteration through the loop has i=2 and j=1. In this case, i > j and keys[j].value.i will indicate that multiples are not allowed. Both conditionals are satisfied so an incorrect error will be given: "parameter '%s' occurs multiple times" This patch replaces the index based check with code that remembers the name of the last parameter seen and only triggers the error case if the current parameter name equals the last one. This works because the list is sorted and duplicate parameters will be grouped together. In reality, we hit this bug while using selective block migration to migrate a guest with 5 disks. 5 was apparently just the right number to push i > j and hit this bug. virsh migrate --live guestname --copy-storage-all --migrate-disks vdb,vdc,vdd,vde,vdf qemu+ssh://dsthost/system Signed-off-by: Jason J.

[libvirt] [PATCH] qemu: reject min_guarantee at parse time
by Cole Robinson 18 Apr '16

18 Apr '16

min_guarantee isn't implemented for qemu, and an explicit check was added in june 2014 to reject the VM at qemu startup time. It's a weird place to do XML validation, so move it to the post parse area where we have similar checks. Also drop a validation check against min_guarantee in the command line building; it will never see min_guarantee there. --- src/qemu/qemu_command.c | 1 - src/qemu/qemu_domain.c | 7 +++++++ src/qemu/qemu_process.c | 7 ------- 3 files changed, 7 insertions(+), 8 deletions(-) diff --git a/src/qemu/qemu_command.c b/src/qemu/qemu_command.c index 26c19ff..2fb967a 100644 --- a/src/qemu/qemu_command.c +++ b/src/qemu/qemu_command.c @@ -9143,7 +9143,6 @@ qemuBuildCommandLineValidate(virQEMUDriverPtr driver, if (virMemoryLimitIsSet(def->mem.hard_limit) || virMemoryLimitIsSet(def->mem.soft_limit) || - def->mem.min_guarantee || virMemoryLimitIsSet(def->mem.swap_hard_limit)) { virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", _("Memory tuning is not available in session mode")); diff --git a/src/qemu/qemu_domain.c b/src/qemu/qemu_domain.c index 73187ce..f5fafc8 100644 --- a/src/qemu/qemu_domain.c +++ b/src/qemu/qemu_domain.c @@ -1690,6 +1690,13 @@ qemuDomainDefPostParse(virDomainDefPtr def, return ret; } + if (def->mem.min_guarantee) { + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", + _("Parameter 'min_guarantee' " + "not supported by QEMU.")); + return -1; + } + if (def->os.loader && def->os.loader->type == VIR_DOMAIN_LOADER_TYPE_PFLASH && def->os.loader->readonly == VIR_TRISTATE_SWITCH_ON && diff --git a/src/qemu/qemu_process.c b/src/qemu/qemu_process.c index 81d86c2..387aff5 100644 --- a/src/qemu/qemu_process.c +++ b/src/qemu/qemu_process.c @@ -4550,13 +4550,6 @@ qemuProcessStartValidate(virQEMUDriverPtr driver, virDomainDefCheckDuplicateDiskInfo(vm->def) < 0) return -1; - if (vm->def->mem.min_guarantee) { - virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", - _("Parameter 'min_guarantee' " - "not supported by QEMU.")); - return -1; - } - VIR_DEBUG("Checking for any possible (non-fatal) issues"); /* -- 2.7.3

[libvirt] [PATCH] tests: Fix syntax in iSCSI auth/secret tests
by John Ferlan 18 Apr '16

18 Apr '16

While working on the tests for the secret initialization vector, I found that the existing iSCSI tests were lacking in how they defined the IQN. Many had IQN's of just 'iqn.1992-01.com.example' for one disk while using 'iqn.1992-01.com.example/1' for the second disk (same for hostdevs - guess how they were copied/generated). Typically (and documented this way), IQN's would include be of the form 'iqn.1992-01.com.example:storage/1' indicating an IQN using "storage" for naming authority specific string and "/1" for the iSCSI LUN. So modify the input XML's to use the more proper format - this of course has a ripple effect on the output XML and the args. Also note that the "%3A" is generated by the virURIFormat/xmlSaveUri to represent the colon.

[libvirt] [PATCH] ZFS: Support sparse volumes
by Richard Laager 17 Apr '16

17 Apr '16

By default, `zfs create -V ...` reserves space for the entire volsize, plus some extra (which attempts to account for overhead). If `zfs create -s -V ...` is used instead, zvols are (fully) sparse. A middle ground (partial allocation) can be achieved with `zfs create -s -o refreservation=... -V ...`. Both libvirt and ZFS support this approach, so the ZFS storage backend should support it.

Look at the code for createVport() - see the 'parent_hoststr' description. When you did a pool-{create|define} for the "poolhba_name", you provided some XML which would search the existing 'scsi_host#' for one that's capable of supporting a vHBA. What that create is supposed to do (at least it does it on the systems I used) is create another 'scsi_host#'. That scsi_host# is then the vHBA - it's *parent* is supposed to be 'scsi_host2' - see my example. On your host perhaps scsi_host3 or scsi_host4. Do either one of those two have the wwnn/wwpn that's in your poolhba_name: <adapter type='fc_host' managed='yes' wwnn='20000120fa8f1271' wwpn='10000090fa8f1271'/> I'm really not quite sure what's happening on your host/environment. Perhaps you could follow how createVport generates things and report back. You can always 'create' another vHBA using a different wwnn/wwpn John

[libvirt] [PATCH] libxl config file convertion: correct `type=netfront' to 'type=vif'
by Chunyan Liu 16 Apr '16

16 Apr '16

According to current xl.cfg docs and xl codes, it uses type=vif instead of type=netfront. Currently after domxml-to-native, libvirt xml model=netfront will be converted to xl type=netfront. This has no problem before, xen codes for a long time just check type=ioemu, if not, set type to _VIF. Since libxl uses parse_nic_config to avoid duplicate codes, it compares 'type=vif' and 'type=ioemu' for valid parameters, others are considered as invalid, thus we have problem with type=netfront in xl config file. #xl create sles12gm-hvm.orig Parsing config from sles12gm-hvm.orig Invalid parameter `type'. Correct the convertion in libvirt, so that it matchs libxl codes and also xl.cfg. Signed-off-by: Chunyan Liu <cyliu(a)suse.com> --- Since type=netfront config has been used for a very long time, at lease for xm/xend, it has no problem.

[libvirt] [PATCH V2] libxl: use LIBXL_API_VERSION 0x040200
by Jim Fehlig 16 Apr '16

16 Apr '16

To ensure the libvirt libxl driver will build with future versions of Xen where the libxl API may change in incompatible ways, explicitly use LIBXL_API_VERSION 0x040200. The libxl driver does use new libxl APIs that have been added since Xen 4.2, but currently it does not make use of any changes made to existing APIs such as libxl_domain_create_restore or libxl_set_vcpuaffinity. The version can be bumped if/when the libxl driver consumes the changed APIs.

[libvirt] Regarding PCI/PCIe Multifunction hotplug support in libvirt
by Shivaprasad bhat 16 Apr '16

16 Apr '16

Hi All, I am exploring how to go about supporting multi-function hot-plug/unplug support from libvirt now that Qemu has enabled it. The Qemu semantics is that, qemu queues the notification to guest until function 0 is hot- plugged and on function 0 hot-plug, all the previously added devices in the slot are notified to the guest. For hot-unplug - On x86, unplug of any device in the slot would unplug all the functions of the slot. On PPC, unplug all non-zero functions first, then unplug the function zero which triggers the unplug of all the functions in the slot. On Libvirt, I had a brief chat with Laine Stump on IRC and we "think" the below semantics would be appropriate. 1) Change the virDomainAttachDeviceFlags() to recognize multiple devices in the XML and the application should make one call to attach all the functions for the slot at one time. 2) The libvirt qemu driver to translate this into multiple attach device commands to qemu with the final operation being for function 0. 3) The XML now needs to accept multiple devices and there is a need for single parent element. I am thinking if we should have all devices to be enclosed in <device></device> parent element. Note that this is only when all the devices should go to the same slot. We probably should disallow user attempting to hot-plug to different slots with this. 4) For the hot-unplug, the application to send all the devices the same way enclosed in <device></devices> and libvirt to go ahead with unplug only if all the devices are specified in the XML for the slot. Want to know if you foresee any problem with using <device></device> semantics Or you have any different approach/suggestions. Any comments greatly appreciated. Thanks and Regards, Shivaprasad

[libvirt] [PATCH v6 0/7] storage:dir: ploop volumes support
by Olga Krishtal 15 Apr '16

15 Apr '16

This series of patches introduces the support of ploop volumes in storage pools (dir, fs, etc). Ploop volume is a disk loopback block device consists of root.hds (it is the image file) and DiskDescriptor.xml: https://openvz.org/Ploop/format. Due to this fact it can't be treated as file or any other volume type, moreover, in order to successfully manipulate with such volume, ploop tools should be installed. All callbacks except the wipeVol are supported. First patch introduces ploop volume type. This is a directory with two files inside. The name of the directory is the name of the volume. Patch 2 deals with creating an empty volume and cloning the existing one. Clone is done via simle cp operation. If any of this operation fails - directory will be deleted. Patch 3 deletes recursively ploop directory. Patch 4 uses ploop tool to resize volume. Patch 6 adapts all refreshing functions to work with ploop. To get information the directory is checked. The volume is treated as the ploops one only if it contains ploop files. Every time the pool is refreshed DiskDescriptor.xml is restored. This is necessary, because the content of the volume may have changed. Upload and download (patch 7) can't be done if the volume contains snapshots. v6: - There is no DiskDescriptor.xml restoring during the refresh pool operation. This operation is moved to storage driver. - fixed issue with regenerating xml for ploop volume with the snapshots. v5: - added ploop volume type - there is no change in opening volume functions. Now reopening takes place is the volume is ploops one. - restore DiskDescriptor.xml every refresh pool - all information, except format is taken from header - forbidden upload and download ops for volume with snapshots - there is no separate function for deleting the volume - fixed identation and leaks v4: - fixed identation issues. - in case of .uploadVol, DiskDescriptor.xml is restored. - added check of ploops'accessibility v3: - no VIR_STORAGE_VOL_PLOOP type any more - adapted all patches according to previous change - fixed comments v2: - fixed memory leak - chenged the return value of all helper functions to 0/-1. Now check for success is smth like that: vir****Ploop() < 0 - fixed some identation issues.
