Hide Forgot
Description of problem: Xen guest is shutdown when first starting libvirtd.service. Version-Release number of selected component (if applicable): kernel-4.9.0-0.rc6.git2.1.fc26.x86_64 libvirt-3.0.0-1.fc26.x86_64 xen-4.8.0-2.fc26.x86_64 How reproducible: Always Steps to Reproduce: 1. Boot Fedora Rawhide system xen hypervisor. 2. Create a vm guest using command "xl create xen-guest.conf" 3. Using “xl list” to check the guest status, login to guest and the guest works OK. 4. Start libvirtd.service, check the guest status by xl list. Actual results: Xen guest is shutdown when executing command "service libvirtd start", the status changing like this: [root@dhcp-10-249 ~]# xl list Name ID Mem VCPUs State Time(s) Domain-0 0 6916 8 r----- 36.4 xen-hvm-32 1 1024 2 -b---- 0.2 [root@dhcp-10-249 ~]# service libvirtd status Redirecting to /bin/systemctl status libvirtd.service ● libvirtd.service - Virtualization daemon Loaded: loaded (/usr/lib/systemd/system/libvirtd.service; enabled; vendor pre Active: inactive (dead) Docs: man:libvirtd(8) http://libvirt.org [root@dhcp-10-249 ~]# service libvirtd start Redirecting to /bin/systemctl start libvirtd.service [root@dhcp-10-249 ~]# xl list Name ID Mem VCPUs State Time(s) Domain-0 0 6916 8 r----- 42.0 xen-hvm-32 1 1024 2 ---ss- 0.4 [root@dhcp-10-249 ~]# xl list Name ID Mem VCPUs State Time(s) Domain-0 0 6916 8 r----- 45.0 xen-hvm-32 1 1024 2 --pss- 0.4 [root@dhcp-10-249 ~]# xl list Name ID Mem VCPUs State Time(s) Domain-0 0 6916 8 r----- 46.3 (null) 1 1024 2 --pss- 0.4 [root@dhcp-10-249 ~]# xl list Name ID Mem VCPUs State Time(s) Domain-0 0 6916 8 r----- 48.0 (null) 1 1024 2 --pss- 0.4 [root@dhcp-10-249 ~]# xl list Name ID Mem VCPUs State Time(s) Domain-0 0 6916 8 r----- 50.0 (null) 1 1024 2 --pss- 0.4 [root@dhcp-10-249 ~]# xl list Name ID Mem VCPUs State Time(s) Domain-0 0 6916 8 r----- 103.6 Expected results: The libvirtd service shouldn't affect xen guest status. Additional information: 1. Creating xen guest again, and then restart or stop/start libvirtd.service again, the guest status isn't affected. So xen guest is shutdown only when first starting libvirtd.service after booting host. 2. The xen guest logs displays the guest is shutdown: Waiting for domain xen-hvm-32 (domid 1) to die [pid 1634] Domain 1 has shut down, reason code 2 0x2 Domain has suspended. Done. Exiting now
This bug appears to have been reported against 'rawhide' during the Fedora 26 development cycle. Changing version to '26'.
Are you still seeing this with latest f26/rawhide packages?
Yes, it still exists on Fedora26 Alpha release.

Okay since this has persisted across releases and in fedora we are largely kvm focused, moving to the upstream tracker and CCing libvirt xen maintainer
FYI, this is fixed with a newer libvirt. I vaguely recall working on it, but was unsuccessful in quickly finding the commit(s). I did verify the fix is in a somewhat older libvirt by doing a test on SLES15 SP2 (xen 4.13, libvirt 6.0.0): # systemctl is-active libvirtd inactive # xl list Name ID Mem VCPUs State Time(s) Domain-0 0 10690 48 r----- 276.5 Xenstore 1 31 1 -b---- 0.1 sle15sp2-hvm 2 4088 4 -b---- 77.0 # systemctl start libvirtd # systemctl is-active libvirtd active ... wait some time just to be sure # xl list Name ID Mem VCPUs State Time(s) Domain-0 0 10690 48 r----- 347.6 Xenstore 1 31 1 -b---- 0.1 sle15sp2-hvm 2 4088 4 -b---- 101.8
