Building Xen 4.4 rpms for centos7
by Pasi Kärkkäinen 10 Feb '15

10 Feb '15

Hello, Now that the Xen 4.4.1 rpms + libvirt 1.2.10 rpms for CentOS 6 seem to be in good shape it would be a good time to start experimenting with el7 builds aswell. I think it's best to start with the same set of packages we have for el6, and just do the minimum required changes to get them working on centos7. That probably means fixing some dependencies in the spec file, and some changes for systemd support. Note that all those changes are already done in Fedora 21 Xen rpms, for example: ftp://ftp.funet.fi/pub/mirrors/fedora.redhat.com/pub/fedora/linux/updates/2… A few months ago I also saw a Xen 4.4 el7 rpms port, so we could find those src.rpms aswell. And then there's the dom0 kernel.. Stock rhel7/centos7 is based on Linux 3.10 kernel, so we probably can use the exact same 3.10.63 kernel we have today for CentOS 6 Xen. Any thoughts? -- Pasi

Re: [CentOS-virt] libguestfs-tools not working

You may be better off with the RHEL / CentOS 7.1 libguestfs packages which are available as a preview. This is a substantial rebase with many more features and somewhat faster too. Follow the instructions here: https://www.redhat.com/archives/libguestfs/2014-May/msg00090.html Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming and virtualization blog: http://rwmj.wordpress.com virt-df lists disk usage of guests without needing to install any software inside the virtual machine. Supports Linux and Windows. http://people.redhat.com/~rjones/virt-df/

libguestfs-tools not working
by Robert Nichols 06 Feb '15

06 Feb '15

In CentOS 6 with KVM, I have libguestfs-tools installed, but the "virt-xxx" tools like "virt-df" just give, "libguestfs: error: cannot find any suitable libguestfs supermin, fixed or old-style appliance on LIBGUESTFS_PATH (search path: /usr/lib64/guestfs)". What am I missing? All the guests boot and run OK. I just can't get these tools to work. libguestfs-tools-1.20.11-11.el6.x86_64 libguestfs-tools-c-1.20.11-11.el6.x86_64 $ ls -lR /usr/lib64/guestfs /usr/lib64/guestfs: total 4 drwxr-xr-x. 2 root root 4096 Dec 3 13:16 supermin.d /usr/lib64/guestfs/supermin.d: total 7020 -rw-r--r--. 1 root root 5171200 Oct 17 11:50 base.img -rw-r--r--. 1 root root 1858048 Oct 17 11:50 daemon.img -rw-r--r--. 1 root root 139401 Oct 17 11:50 hostfiles -rw-r--r--. 1 root root 4608 Oct 17 11:50 init.img -rw-r--r--. 1 root root 2048 Oct 17 11:50 udev-rules.img -- Bob Nichols "NOSPAM" is really part of my email address.

Using network-script with Xen 4.4.1 (aka what will I do without xend?)
by Gene 01 Feb '15

01 Feb '15

I normally use the network-script parameter in the '/etc/xen/xend-config.sxp' configuration file to configure network bridges. However, the latest release of Xen4CentOS (which comes with Xen 4.4.1) has xend disabled by default. Can I continue to use network-script without xend? If not what is the recommended method for automatically configuring network bridges with the latest release of Xen4CentOS? I know I can just enable xend to continue using this script, but since Xen 4.5 is apparently dropping xend altogether I figure I should change my standard configuration starting now. Thanks in advance for your time. -Gene
