similar to: [PATCH v2v] v2v: Set the number of vCPUs to same as host number of pCPUs.

If the thing using parallel CPUs in the guest is doing I/O you'd likely want to tune storage at

This helps mkinitrd which runs pigz (parallel gzip).

Hi, I was trying to migrate some VM's to Virtio-SCSI block devices, as this gives some advantages. While checking the virt-v2v code, I found out that it supported Virtio-SCSI, but some bits were missing. In attachment a small patch that adds the missing bits :) Best regards Jean-Louis

Currently the tests fail on x86 with recent kernels: FAIL: test-255-disks.sh This confused me for a while because our other test program (utils/max-disks/max-disks.pl) reports that it should be possible to add 255 disks. Well it turns out that the default amount of appliance memory is sufficient if you're just adding disks, but if you try to add _and_ partition those disks there's

Instead of creating Guestfs handles and manually apply common options (e.g. debug and trace), use the open_guestfs in Common_utils. This also applies the common options to handles which didn't set them before, so we can inspect also their messages if needed. --- builder/builder.ml | 8 ++------ customize/customize_main.ml | 4 +--- dib/dib.ml | 4 +---

The 'may' function is a higher-order function (HOF) that replaces: match x with | None -> () | Some x -> f x with: may f x The idea comes from lablgtk (OCaml Gtk bindings) where it is widely used. If this change is clearer than previous code, then this could be used in many more places. However I previously steered clear from using HOFs like this because they can be

Make sure that -x enables tracing and -v enables verbose mode, just like other tools do.

Hey, I am getting this error after using virt-v2v-copy-to-local and trying to run: $ virt-v2v -i libvirtxml rhel7.xml -o local -os /var/tmp -of raw I try to set: export LIBGUESTFS_BACKEND_SETTINGS=virbr0=ovirtmgmt with no success and the file /etc/qemu/bridge.conf contains: allow virbr0 it only worked after creating the bridge, is there other way to import without creating the bridge? Thank

Make print_version_and_exit, long_options, display_short_options, and display_long_options private, as set_standard_options now takes care of handling the job for the common command line options. --- mllib/common_utils.mli | 10 ---------- 1 file changed, 10 deletions(-) diff --git a/mllib/common_utils.mli b/mllib/common_utils.mli index 79032bc..24f8f83 100644 --- a/mllib/common_utils.mli +++

v3 -> v4: - Pushed the first patch upstream since it was ACKed. - Prevent use of M except for the special virt-v2v options. - Sort the options after added --help etc. - Make corresponding fixes to the tests. Rich.

v2 -> v3: - Add M variant and test it. Rich.

In Std_utils we already extend Char and String. These commits take it a little further by extending List and adding a new Option submodule. All basically simple refactoring. Rich.

Hi List, I have a server with two QuadCore 2.93Ghz processors and 16GB Ram, running Debian etch and Xen 3.2-1. Until yesterday I had in this server 2 hvm virtual machines, running w2k, 4 vcpus each without any problem, the use of each virtual machine rarely reach 70%. Today I cloned one of the virtual machines and started they with 2 vcpus, right after I start this new guest the use of cpus
