hi guys,   happy new year!!!  I encountered  a problem when we used virt-df command to display my guest disks useage. the virt-df command from pkg libguestfs-tools-c-1.36.3-6.el7_4.3.x86_64,version is  virt-df --version : virt-df 1.36.3rhel=7,release=6.el7_4.3,libvirt the output in guest with the method referred in http://libguestfs.org/virt-df.1.html#STATVFS NUMBERS is:

v2 -> v3: - Drop gnulib fallback.

It started out as "this'll be just a simple fix ..." and turned into something a bit over-engineered in the end. Here it is anyway. Rich.

v1 -> v2: - Removed the f_type field from StatVFS.statvfs structure. - New function StatVFS.filesystem_is_remote, written in C. [Thinking about it, this should probably be called ?is_network_filesystem?, but I can change that before pushing]. - Use statvfs instead of fstatvfs, and statfs instead of fstatfs. - Rejigged the comments in builder/builder.ml to make them simpler

[Jim, as coreutils developer, this might interest you] In libguestfs we run some quite detailed checks of the output of the statvfs system call for our tool "virt-df". I noticed that the output of virt-df changed slightly. Narrowing it down, the difference only happens between: Fedora kernel 3.2.0-0.rc0.git4.1.fc17 (3rd Nov) Fedora kernel 3.2.0-0.rc1.git2.1.fc17 (11th Nov) With

hi Jones, Sorry for the late reply. when I used your method to execute command: $guestfish -N fs:xfs -m /dev/sda1 statvfs / libguestfs: error: mkfs: xfs: /dev/sda1: mkfs.xfs: No such file or directory guestfish: error creating prepared disk image 'fs:xfs' on 'test1.img': failed to create filesystem (xfs): mkfs: xfs: /dev/sda1: mkfs.xfs: No such file or directory does I need to

This option prints the estimated size of the data that will be copied from the source disk. For interest, the test prints: 3747840 ../test-data/phony-guests/windows.img Estimate: 3710976 --- v2v/Makefile.am | 2 ++ v2v/cmdline.ml | 17 ++++++++++-- v2v/cmdline.mli | 2 ++ v2v/test-v2v-print-estimate.sh | 47 +++++++++++++++++++++++++++++++++

Hi, I'm having a similar problem, I get "The cluster size in this system is not supported." I get this when running wine InstMsiA.exe (using the version from microsoft.com). It comes up in a windows message box. I'm running wine from yesterday's cvs. I tried running Rein's test program from this old email and I get the following output: % wine fds 'c:\'

This series is an attempt to add a mode of virt-v2v operation where it leaves the config and disk image conversion, rollback on errors, registering with the destination hypervisor, etc. to a third-party toolset, and performs only tuning of the guest OS to run in the KVM-based hypervisor.

after install libguestfs_xfs, all results are: [using guestfish] guestfish -N fs:xfs -m /dev/sda1 statvfs / bsize: 4096 frsize: 4096 blocks: 24713 bfree: 23391 bavail: 23391 files: 51136 ffree: 51133 favail: 51133 fsid: 2049 flag: 4096 namemax: 255 [using virt-rescure] virt-rescue -a test1.img ><rescue> mount /dev/sda1 /sysroot ><rescue> stat -f /sysroot File:

I thought it would be easy to rewrite virt-make-fs in C. Two days later ... The Perl program uses a lot of external commands, which makes it pretty tedious to implement in C. Rich.

- move the space needed by mountpoint mapping to an own function, outside of the checking loop - remove the minimum limit of 100M on partitions, since existing partitions that we check (e.g. /boot) may be smaller than that - in case /boot is not on a separate mountpoint, enforce the space check on the root mountpoint instead, since it is where /boot is in that case --- v2v/v2v.ml | 55

Factor the size checks out to separate functions.

This series is a second attempt to add a mode of virt-v2v operation where it leaves the config and disk image conversion, rollback on errors, registering with the destination hypervisor, etc. to a third-party toolset, and performs only tuning of the guest OS to run in the KVM-based hypervisor. The first 14 patches are just refactoring and rearrangement of the code, factoring the implementation

common/mlutils: Unix_utils.StatVFS.statvfs: This commit implements a full-featured binding for the statvfs(3) function. We then use this to reimplement the daemon statvfs API in OCaml. Note that the Gnulib fallback is fixed in this commit. It previously referenced non-existent field names in the fs_usage struct. --- common/mlutils/unix_utils-c.c | 138 ++++++++++++++++++++++++++++---
