[libvirt] PATCH: Include port number with virtio serial devices

[libvirt] [PATCH] Adds the missing vol-pool command to virsh.
by Justin Clift 08 Jun '10

08 Jun '10

Hi all, This patch adds a "vol-pool" command to virsh, to round out the conversion functions for vols in virsh. At the moment, if we start with a volume name and a pool id, we're all good. We can convert from that pair to either a volume key or volume path. But, if we're given just a volume key or path we have no good way to look up the storage pool for it. Kind of makes it a one way association. :/ This patch fixes that, making it possible to work from just having a volume key or path. :) Regards and best wishes, Justin Clift --- tools/virsh.c | 48 ++++++++++++++++++++++++++++++++++++++++++++++++ 1 files changed, 48 insertions(+), 0 deletions(-) diff --git a/tools/virsh.c b/tools/virsh.c index 1279f41..95aea0f 100644 --- a/tools/virsh.c +++ b/tools/virsh.c @@ -5975,6 +5975,53 @@ cmdVolName(vshControl *ctl, const vshCmd *cmd) } +/* + * "vol-pool" command + */ +static const vshCmdInfo info_vol_pool[] = { + {"help", N_("returns the storage pool for a given volume key or path")}, + {"desc", ""}, + {NULL, NULL} +}; + +static const vshCmdOptDef opts_vol_pool[] = { + {"vol", VSH_OT_DATA, VSH_OFLAG_REQ, N_("volume key or path")}, + {NULL, 0, 0, NULL} +}; + +static int +cmdVolPool(vshControl *ctl, const vshCmd *cmd) +{ + virStoragePoolPtr pool; + virStorageVolPtr vol; + + // Check the connection to libvirtd daemon is still working + if (!vshConnectionUsability(ctl, ctl->conn, TRUE)) + return FALSE; + + // Use the supplied string to locate the volume + if (!(vol = vshCommandOptVolBy(ctl, cmd, "vol", "pool", NULL, + VSH_BYUUID))) { + return FALSE; + } + + // Look up the parent storage pool for the volume + pool = virStoragePoolLookupByVolume(vol); + if (pool == NULL) { + vshError(ctl, "%s", _("failed to get parent pool")); + virStorageVolFree(vol); + return FALSE; + } + + // Return the name of the parent storage pool + vshPrint(ctl, "%s\n", virStoragePoolGetName(pool)); + + // Cleanup + virStorageVolFree(vol); + virStoragePoolFree(pool); + return TRUE; +} + /* * "vol-key" command @@ -8837,6 +8884,7 @@ static const vshCmdDef commands[] = { {"vol-dumpxml", cmdVolDumpXML, opts_vol_dumpxml, info_vol_dumpxml}, {"vol-info", cmdVolInfo, opts_vol_info, info_vol_info}, {"vol-list", cmdVolList, opts_vol_list, info_vol_list}, + {"vol-pool", cmdVolPool, opts_vol_pool, info_vol_pool}, {"vol-path", cmdVolPath, opts_vol_path, info_vol_path}, {"vol-name", cmdVolName, opts_vol_name, info_vol_name}, {"vol-key", cmdVolKey, opts_vol_key, info_vol_key}, -- 1.7.0.1

I did that and found out that it is the boot=on drive option that is the cause of the problem: -drive file=/root/SLES-10.3.img,if=ide,index=0,boot=on For some reason it only works when it is set to boot=off.

[libvirt] [PATCH] 0/10AppArmor driver updates
by Jamie Strandboge 08 Jun '10

08 Jun '10

This patch series addresses bug fixes in the AppArmor driver as well as updating it to changes made in 0.7.6 and 0.7.7. All of these are self-contained within the driver except 4_qemu_driver_stdin_path.patch. This is required by 5_apparmor-fix-save-restore.patch (see below). These all pass 'make syntax-check' and 'make check' (except 'daemon-conf', which has never passed here and I didn't patch it). 1_apparmor-dont-clear-caps.patch: originally submitted on 2010/02/08 with no feedback. The calls to virExec() in security_apparmor.c when invoking virt-aa-helper use VIR_EXEC_CLEAR_CAPS. When compiled without libcap-ng, this is not a problem (it's effectively a no-op) but with libcap-ng this causes MAC_ADMIN to be cleared. MAC_ADMIN is needed by virt-aa-helper to manipulate apparmor profiles and without it VMs will not start[1]. This patch calls virExec with the default VIR_EXEC_NONE instead. 2_apparmor-remove-unloaded-profile-is-not-fatal.patch: Don't exit with error if the user unloaded the profile outside of libvirt[2] 3_apparmor-fix-vah-xml-parse.patch: add VIR_DOMAIN_XML_INACTIVE flag to virDomainDefParseString() so virDomainDefParseString() doesn't error out when seeing <seclabel...>. This was needed due to changes since 0.7.5. 4_qemu_driver_stdin_path.patch: adjust args to qemudStartVMDaemon() to also specify path to stdin_fd, so this can be passed to the AppArmor driver via *SetSecurityAllLabel(). This updates all calls to qemudStartVMDaemon() as well as setting up the non-AppArmor security driver *SetSecurityAllLabel() declarations for the above. This is required for 5_apparmor-fix-save-restore.patch since AppArmor resolves the passed file descriptor to the pathname given to open(). 5_apparmor-fix-save-restore.patch: refactoring to update AppArmor security driver to adjust profile for save/restore[3] 6_apparmor-fix-backingstore.patch: adjust virt-aa-helper to handle backing store[4] 7_apparmor-fix-hostdev.patch: adjust virt-aa-helper to handle pci devices. Update valid_path() to have an override array to check against, and add "/sys/devices/pci" to it. Then rename file_iterate_cb() to file_iterate_hostdev_cb() and create file_iterate_pci_cb() based on it. 8_apparmor-fix-xauth.patch: adjust virt-aa-helper to handle SDL graphics, specifically Xauthority[6]. Also remove a couple redundant checks 9_apparmor-examples.patch: adjustments to the example profiles 10_apparmor-vah-test.patch: update pcidev test and add SDL xauth [1] https://launchpad.net/bugs/517714 [2] https://launchpad.net/bugs/530400 [3] https://launchpad.net/bugs/457716 [4] https://launchpad.net/bugs/470636 [5] https://launchpad.net/bugs/545795 [6] https://launchpad.net/bugs/545426 -- Jamie Strandboge | http://www.canonical.com

Hi all, make syntax-check is reporting an error with the AUTHORS file, which seems to be coming from an incorrect address for Jim Fehlig. $ make syntax-check GFDL_version 2.60 GFDL_version TAB_in_indentation 0.03 TAB_in_indentation Wundef_boolean 0.25 Wundef_boolean avoid_ctype_macros 0.14 avoid_ctype_macros avoid_if_before_free 7.60 avoid_if_before_free avoid_write 0.03 avoid_write cast_of_argument_to_free 0.12 cast_of_argument_to_free cast_of_x_alloc_return_value 0.11 cast_of_x_alloc_return_value changelog 0.02 changelog check_author_list jfehlig(a)linux-ypgk.site maint.mk: committer(s) not listed in AUTHORS make: *** [sc_check_author_list] Error 1 $ This is the git log entry it may be from: commit b1eb7f2e987d21b1711e86e5cb63a69abfce82f1 Author: Jim Fehlig <jfehlig(a)linux-ypgk.site> Date: Fri Jun 4 10:04:03 2010 -0600 Fixes for commit 211dd1e9 Fixes for issues in commit 211dd1e9 noted by by Jim Meyering. 1. Allocate content buffer of size content_length + 1 to ensure NUL-termination. 2. Limit content buffer size to 64k 3. Fix whitespace issue V2: - Add comment to clarify allocation of content buffer - Add ATTRIBUTE_NONNULL where appropriate - User NULLSTR macro Adding the incorrect email to the AUTHORS file is a workaround, but is someone ok to fix the cause?
