Re: [CentOS] CentOS 7 KVM guests no longer get keystrokes after yum update [solved]
by Charles Polisher 29 Dec '14

Fixed. I had installed a preview repository from Red Hat for some not-yet-released libguestfs features (libguestfs-RHEL-7.1-preview). There were evidently changes to some release packages in the updates repository that were incompatible with the candidate packages in the preview repository cited above. I disabled the preview repo in /etc/yum.repos.d/..., uninstalled each of its packages, and re-installed the relevant packages (libvirt qemu-kvm qemu-kvm-tools virt-* spice-gtk spice-gtk-python spice-gtk-tools spice-gtk3-vala spice-xpi). Lesson learned: When you install 3rd party repositories you should reserve time for hand-holding your package management system. -- Charles Polisher

OT: Bittorrent clients
by Sorin Srbu 29 Dec '14

29 Dec '14

Hi all, Just switched my home computer from Windows 7 to CentOS 6.6 and I'm having a slight bit of trouble with the bittorrent-clients. * Transmission is fine but lacks "a bit" in features. * Vuze is my preferred bt-client but gives me horrendous gfx-artifacts, like not showing the torrent name (it's white text on a white background or some such...). * Deluge is better, and what I'm using now, but I'm having trouble finding a repo that has the updated versions available for install with yum. I installed v1.3.5 a few days ago and already it's telling me that version is way outdated. Would anybody have any hints as to how and where to get the latest Deluge for CentOS? Or maybe even suggest a better torrent-client? All I'm getting from the Deluge site is some kind of source packages that is of no use for me. 8-/ Thanks in advance for any hints, tips and tricks. -- /Sorin

CentOS 7 KVM guests no longer get keystrokes after yum update
by Charles Polisher 28 Dec '14

28 Dec '14

Dear all, After "yum update" and reboot on a CentOS 7 server running kvm, all VM guests fail to receive keyboard input. Even sending ctrl-alt-delete from the virt-manager "Send Key" menu is inoperative. Most guests are set up as spice + QXL, and viewed on remote X sessions using virt-manager. Extensive browsing for a solution has turned up only dead ends. I tried reverting to the earlier kernel but there was no joy. Possibly I made some config change or installed (or removed) something that didn't take effect until I rebooted, but searching the host's command history has been unhelpful. Has anyone here run into this? Connecting to a CentOS 6 guest with virt-viewer writes some messages to the console, but what little I found in a web search was unhelpful. BTW, I hadn't messed with any guest keymaps, all stock installs with en_US. $ virt-viewer irc.foo.peecee3.com (virt-viewer:6016): GSpice-WARNING **: Warning no automount- inhibiting implementation available (virt-viewer:6016): vnc-keymap-WARNING **: Unknown keycode mapping '(null)'. Please report to gtk-vnc-list(a)gnome.org including the following information: - Operating system - GDK build - X11 Server - xprop -root - xdpyinfo Every attempted keystroke on the guest produces one of these messages: (virt-viewer:6016): GSpice-CRITICAL **: send_key: assertion `scancode != 0' failed What I think is relevant, running on the most recent kernel, all commands run from the host: $ libvirtd --version libvirtd (libvirt) 1.2.8 $ uname -a Linux mencius.peecee3.com 3.10.0-123.13.2.el7.x86_64 #1 SMP Thu Dec 18 14:09:13 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux $ cat /etc/redhat-release CentOS Linux release 7.0.1406 (Core) $ systemctl --no-pager list-unit-files 2>&1| egrep -i 'spice|agent|virt|qxl|qemu|kvm' | grep -v '\.socket' machine-qemu\x2dirc.foo.peecee3.com.scope static libvirt-guests.service disabled libvirtd.service enabled virt-who.service disabled virtlockd.service static $ localectl status System Locale: LANG=en_US.UTF-8 VC Keymap: us X11 Layout: us $ rpm -qa | egrep -i 'spice|agent|virt|qxl|qemu|kvm' | sort ipxe-roms-qemu-20130517-5.gitc4bce43.el7.noarch libgovirt-0.1.0-3.el7.x86_64 libvirt-1.2.8-9.el7.x86_64 libvirt-client-1.2.8-9.el7.x86_64 libvirt-daemon-1.2.8-9.el7.x86_64 libvirt-daemon-config-network-1.2.8-9.el7.x86_64 libvirt-daemon-config-nwfilter-1.2.8-9.el7.x86_64 libvirt-daemon-driver-interface-1.2.8-9.el7.x86_64 libvirt-daemon-driver-lxc-1.2.8-9.el7.x86_64 libvirt-daemon-driver-network-1.2.8-9.el7.x86_64 libvirt-daemon-driver-nodedev-1.2.8-9.el7.x86_64 libvirt-daemon-driver-nwfilter-1.2.8-9.el7.x86_64 libvirt-daemon-driver-qemu-1.2.8-9.el7.x86_64 libvirt-daemon-driver-secret-1.2.8-9.el7.x86_64 libvirt-daemon-driver-storage-1.2.8-9.el7.x86_64 libvirt-daemon-kvm-1.2.8-9.el7.x86_64 libvirt-glib-0.1.7-3.el7.x86_64 libvirt-python-1.2.8-5.el7.x86_64 perl-Sys-Virt-1.1.1-5.el7.x86_64 qemu-img-rhev-2.1.2-13.el7.x86_64 qemu-kvm-common-rhev-2.1.2-13.el7.x86_64 qemu-kvm-rhev-2.1.2-13.el7.x86_64 qemu-kvm-tools-rhev-2.1.2-13.el7.x86_64 spice-glib-0.20-8.el7.x86_64 spice-gtk3-0.20-8.el7.x86_64 spice-protocol-0.12.6-2.el7.noarch spice-server-0.12.4-5.el7_0.1.x86_64 virt-install-1.0.1-1.el7.centos.noarch virt-manager-1.0.1-1.el7.centos.noarch virt-manager-common-1.0.1-1.el7.centos.noarch virt-top-1.0.8-7.el7.x86_64 virt-viewer-0.5.7-7.el7.x86_64 virt-what-1.13-5.el7.x86_64 virt-who-0.8-15.el7_0.noarch Ordinarily selinux run on the host, but I temporarily disabled it to facilitate problem solving: $ getenforce Disabled The qemu logs for the guests are unremarkable, and nothing much shows up in /var/log/messages.

I would suggest looking at the mailer daemon logs on both the sending and receiving systems. It would appear that the sending system is having difficulties at the receiving system end.

Robert, If you never changed fail2ban defaults you probably had email aliases defined somewhere in your configurations. Whatever you had it was incorrect and it's not worth the effort to figure out why it ever worked if at all. The "right" way is to use email addresses in (at least locally) routable domains.
