[libvirt-users] Windows guest skipping chkdsk if using Spice display
by Gionatan Danti 05 Nov '18

Hi all, as per subject, when a Windows guest using a Spice display is rebooted with a planned chkdsk, the consistency check is always skipped. It seems that the Spice display issues some "phantom" keystrokes, which are then intended by Windows as the "skip chkdsk at boot" signal. I tried to use a Spice display with no additional features (ie: USB redirection), but to no avail. To workaround the problem I must use a VNC display, which is less featureful than the Spice one. My system and package versions are: CentOS 7.5 x86-64 spice-gtk3-0.34-3.el7_5.1.x86_64 spice-server-0.14.0-2.el7_5.4.x86_64 spice-glib-0.34-3.el7_5.1.x86_64 libvirt-3.9.0-14.el7_5.7.x86_64 qemu-kvm-ev-2.10.0-21.el7_5.4.1.x86_64 It seems I am not the only one experiencing this problem: http://seifesrants.blogspot.com/2016/07/ghost-keystrokes-with-libvirt-kvm-s… Any suggestion?

[libvirt-users] How to change the default connection of 'virsh' tool from 'qemu' to 'xen' ?
by Minjun Hong 02 Nov '18

Hi. Thanks to help of this mailing list (especially Jim Fehlig), I have finished setup of libvirt. However, there is something weird. It is that I installed libvirt on 5 servers but the default connection of one of them is 'qemu:///' even if those of the others are all 'xen:///'. I searched how to change it but, I only found a bypass adding " LIBVIRT_DEFAULT_URI='xen:///' " in my .bashrc file. Currently, value of the variable (LIBVIRT_DEFAULT_URI) is set to 'qemu:///'. Since the bypass makes the virtualization type of the server visible 'qemu' to the open stack, I have to change libvirt configuration. I also checked some configure files under '/etc/libvirt', such as libvirt.conf, libvirtd.conf and libxl.conf. But I have no idea, how and what to change. Please give me some advise. It will be a big help for me. Thanks.
