[PATCH] aarch64: appliance: Use AAVMF (UEFI) if available for running the appliance.
by Richard W.M. Jones 21 Jan '15

21 Jan '15

From: "Richard W.M. Jones" <rjones(a)redhat.com> AAVMF is an open source UEFI implementation for aarch64 based on OVMF. As aarch64 is heading for requiring UEFI even inside guests, if the AAVMF firmware is installed on the host, use it as a hint that we should boot the guest using AAVMF instead of the default "empty machine". Note this requires very recent AAVMF, libvirt, qemu. However that's OK since it's only applicable to aarch64. On non-aarch64, this patch does nothing. Thanks: Laszlo Ersek for a lot of help getting this right. --- src/appliance.c | 66 +++++++++++++++++++++++++++++++++++++++++++++++++- src/guestfs-internal.h | 1 + src/launch-direct.c | 14 +++++++++++ src/launch-libvirt.c | 25 +++++++++++++++++++ 4 files changed, 105 insertions(+), 1 deletion(-) diff --git a/src/appliance.c b/src/appliance.c index d7aa6b1..5fa47f2 100644 --- a/src/appliance.c +++ b/src/appliance.c @@ -1,5 +1,5 @@ /* libguestfs - * Copyright (C) 2010-2012 Red Hat Inc. + * Copyright (C) 2010-2014 Red Hat Inc. * * This library is free software; you can redistribute it and/or * modify it under the terms of the GNU Lesser General Public @@ -459,3 +459,67 @@ dir_contains_files (const char *dir, ...) va_end (args); return 1; } + +#ifdef __aarch64__ + +#define AAVMF_DIR "/usr/share/AAVMF" + +/* Return the location of firmware needed to boot the appliance.

[PATCH] daemon: use btrfs(1) to get btrfs labels
by Pino Toscano 19 Jan '15

19 Jan '15

blkid(1) (or actually, libblkid) seems to handle file system labels up to 127 characters. Considering that btrfs labels can be up to 255 characters, this means long labels are not read correctly (i.e. get truncated) by blkid. Get the file system type, and if btrfs is available invoke `btrfs filesystem` to get the label of btrfs file systems. --- daemon/blkid.c | 6 ++++++ daemon/btrfs.c | 24 ++++++++++++++++++++++++ daemon/daemon.h | 3 +++ 3 files changed, 33 insertions(+) diff --git a/daemon/blkid.c b/daemon/blkid.c index b98c155..2c9e2f1 100644 --- a/daemon/blkid.c +++ b/daemon/blkid.c @@ -26,6 +26,7 @@ #include "daemon.h" #include "actions.h" +#include "optgroups.h" GUESTFSD_EXT_CMD(str_blkid, blkid); @@ -76,6 +77,11 @@ do_vfs_type (const mountable_t *mountable) char * do_vfs_label (const mountable_t *mountable) { + CLEANUP_FREE char *type = do_vfs_type (mountable); + + if (type && STREQ (type, "btrfs") && optgroup_btrfs_available ()) + return btrfs_get_label (mountable->device); + return get_blkid_tag (mountable->device, "LABEL"); } diff --git a/daemon/btrfs.c b/daemon/btrfs.c index 150c089..cf1507d 100644 --- a/daemon/btrfs.c +++ b/daemon/btrfs.c @@ -44,6 +44,30 @@ optgroup_btrfs_available (void) return prog_exists (str_btrfs) && filesystem_available ("btrfs") > 0; } +char * +btrfs_get_label (const char *device) +{ + int r; + CLEANUP_FREE char *err = NULL; + char *out = NULL; + size_t len; + + r = command (&out, &err, str_btrfs, "filesystem", "label", + device, NULL); + if (r == -1) { + reply_with_error ("%s", err); + free (out); + return NULL; + } + + /* Trim trailing \n if present. */ + len = strlen (out); + if (len > 0 && out[len-1] == '\n') + out[len-1] = '\0'; + + return out; +} + /* Takes optional arguments, consult optargs_bitmask. */ int do_btrfs_filesystem_resize (const char *filesystem, int64_t size) diff --git a/daemon/daemon.h b/daemon/daemon.h index c101c3b..cf123bf 100644 --- a/daemon/daemon.h +++ b/daemon/daemon.h @@ -232,6 +232,9 @@ extern void wipe_device_before_mkfs (const char *device); extern void aug_read_version (void); extern void aug_finalize (void); +/*-- in btrfs.c --*/ +extern char *btrfs_get_label (const char *device); + /* The version of augeas, saved as: * (MAJOR << 16) | (MINOR << 8) | PATCH */ -- 1.9.3

Since systemd 209, all the functionalities of the former libsystemd-* (including libsystemd-journal) have been merged into a single libsystemd, with the former libraries left as compatibility ones.

[PATCH] mkfs: add 'label' optional argument
by Pino Toscano 19 Jan '15

19 Jan '15

Add the 'label' optional argument to the mkfs action, so it is possible to set a filesystem label direct when creating it. There may be filesystems not supporting changing the label of existing filesystems but only setting it at creation time, so this new optarg will help. Implement it for the most common filesystems (ext*, fat, ntfs, btrfs, xfs), giving an error for all the others, just like set_label does. --- daemon/mkfs.c | 45 +++++++++++++++++++++++++++++++++++++++++++-- generator/actions.ml | 42 +++++++++++++++++++++++------------------- 2 files changed, 66 insertions(+), 21 deletions(-) diff --git a/daemon/mkfs.c b/daemon/mkfs.c index 95ab874..2994307 100644 --- a/daemon/mkfs.c +++ b/daemon/mkfs.c @@ -36,7 +36,7 @@ GUESTFSD_EXT_CMD(str_mkfs, mkfs);

Issue with Libguestfs
by Thirumalai Nambi 19 Jan '15

19 Jan '15

Hi, I'm using SolusVM control panel to create KVM VPS. Suddenly, I can't make any VPS on Host-Node. Their build log says the SolusVM can't read the libguestfs in server. During the debug, I've tried to mount existing VPS using guestmount command and I can't mount the KVM image. Please check here. ============= [root@SG01KVM256-01 ~]# guestmount -i -a /dev/sgkvm256/kvm104_img /mnt libguestfs: error: guestfs_launch failed. See http://libguestfs.org/guestfs-faq.1.html#debugging-libguestfs and/or run 'libguestfs-test-tool'.

[PATCH 0/5] btrfs: add API for btrfs filesystem, check and scrub
by Hu Tao 16 Jan '15

16 Jan '15

Hi, There is one problem: btrfs_filesystem_set_label just doesnt work, giving error message: libguestfs: error: btrfs_filesystem_set_label: /: ERROR: unable to set label Bad address I'm almost sure the patch has no problem, but can't figure out what's the cause. So patch 5 is only for review. Other APIs have no problem. Regards, Hu Hu Tao (5): New API: btrfs_scrub New API: btrfs_check New API: btrfs_filesystem_get_label New API: add btrfs_filesystem_defragment New API: btrfs_filesystem_set_label daemon/btrfs.c | 153 +++++++++++++++++++++++++++++++++++++++++++++++++++ generator/actions.ml | 82 +++++++++++++++++++++++++++ src/MAX_PROC_NR | 2 +- 3 files changed, 236 insertions(+), 1 deletion(-) -- 2.2.1
