The Virtual Machine Manager (virt-manager for short) is a desktop application for managing virtual machines. Since it uses libvirt, it is capable of managing machines from any hypervisor supported by libvirt. Xen is the current primary target. The application's views provide summaries and detailed statistics on performance and resource utilization. A wizard facilitates creation of new guest domains, both para-virtualized and fully-virtualized. Console access is enabled either to a text based serial console or fully graphical access via an embedded VNC client. License: GNU General Public License (GPL)Changes:
This is a bug fix release. The sizing of the VNCwindow was fixed for screens where the physicalsize is less than the guest screen size. The "newvm" button is switched back to its old moreobvious style and placement. Restoration of VMs isworking again for local connections. A menu forsending special key sequences to the guest isadded. Lots of other miscellaneous bugs werefixed.
My RHEL virtual Machine Does not have Virtual Machine Manager Desktop Tool
Hi,
I don't seem to have the Virtual Machine Manager Desktop tool set up on my RHEL6 Machine. The Linux machine runs off VMWare player and I'm not sure whether it is a VMWare software issue or a problem with the RHEL6... (2 Replies)
virt-tar(1) Virtualization Support virt-tar(1)NAME
virt-tar - Extract or upload files to a virtual machine
SYNOPSIS
virt-tar [--options] -x domname directory tarball
virt-tar [--options] -u domname tarball directory
virt-tar [--options] disk.img [disk.img ...] -x directory tarball
virt-tar [--options] disk.img [disk.img ...] -u tarball directory
OBSOLETE
This tool is obsolete. Use virt-copy-in(1), virt-copy-out(1), virt-tar-in(1), virt-tar-out(1) as replacements.
EXAMPLES
Download "/home" from the VM into a local tarball:
virt-tar -x domname /home home.tar
virt-tar -zx domname /home home.tar.gz
Upload a local tarball and unpack it inside "/tmp" in the VM:
virt-tar -u domname uploadstuff.tar /tmp
virt-tar -zu domname uploadstuff.tar.gz /tmp
WARNING
You must not use "virt-tar" with the -u option (upload) on live virtual machines. If you do this, you risk disk corruption in the VM.
"virt-tar" tries to stop you from doing this, but doesn't catch all cases.
You can use -x (extract) on live virtual machines, but you might get inconsistent results or errors if there is filesystem activity inside
the VM. If the live VM is synched and quiescent, then "virt-tar" will usually work, but the only way to guarantee consistent results is if
the virtual machine is shut down.
DESCRIPTION
"virt-tar" is a general purpose archive tool for downloading and uploading parts of a guest filesystem. There are many possibilities:
making backups, uploading data files, snooping on guest activity, fixing or customizing guests, etc.
If you want to just view a single file, use virt-cat(1). If you just want to edit a single file, use virt-edit(1). For more complex cases
you should look at the guestfish(1) tool.
There are two modes of operation: -x (eXtract) downloads a directory and its contents (recursively) from the virtual machine into a local
tarball. -u uploads from a local tarball, unpacking it into a directory inside the virtual machine. You cannot use these two options
together.
In addition, you may need to use the -z (gZip) option to enable compression. When uploading, you have to specify -z if the upload file is
compressed because virt-tar won't detect this on its own.
"virt-tar" can only handle tar (optionally gzipped) format tarballs. For example it cannot do PKZip files or bzip2 compression. If you
want that then you'll have to rebuild the tarballs yourself. (This is a limitation of the libguestfs(3) API).
OPTIONS --help
Display brief help.
--version
Display version number and exit.
-c URI
--connect URI
If using libvirt, connect to the given URI. If omitted, then we connect to the default libvirt hypervisor.
If you specify guest block devices directly, then libvirt is not used at all.
--format raw
Specify the format of disk images given on the command line. If this is omitted then the format is autodetected from the content of
the disk image.
If disk images are requested from libvirt, then this program asks libvirt for this information. In this case, the value of the format
parameter is ignored.
If working with untrusted raw-format guest disk images, you should ensure the format is always specified.
-x
--extract
--download
-u
--upload
Use -x to extract (download) a directory from a virtual machine to a local tarball.
Use -u to upload and unpack from a local tarball into a virtual machine. Please read the "WARNING" section above before using this
option.
You must specify exactly one of these options.
-z
--gzip
Specify that the input or output tarball is gzip-compressed.
SHELL QUOTING
Libvirt guest names can contain arbitrary characters, some of which have meaning to the shell such as "#" and space. You may need to quote
or escape these characters on the command line. See the shell manual page sh(1) for details.
