Sorry, forgot to look into my log for some reason. The log shows the issue being caused by a memory allocation failure. I have however not the slightest clue, where qemu gets the expression, that it should allocate 16GB memory. I’ve configured 5. This is hugeadm --explain directly before qemu invocation followed by Seabios log. Using the recommended settings as suggested seems to freeze the host. Sysreq does not work after reattaching the keyboard. I’ve also used the 5 1GB Hugepages before in default runlevel. The used memory is then at 80%, but nothing critical. Maybe it’s related to x-igd-gms? Although the memory obviously is already stolen. It happens usually before or shortly after the login screen is shown. No idea, why it never happened before, but perhaps libvirt enforces some cgroup constrains on the memory usage. hugeadm: Thu Sep 7 19:53:37 CEST 2017 Total System Memory: 6983 MB Mount Point Options /var/lib/hugetlbfs rw,relatime,pagesize=1073741824 /var/lib/hugetlbfs/user/qemu/pagesize-1GB rw,relatime,pagesize=1073741824 Huge page pools: Size Minimum Current Maximum Default 1073741824 5 5 5 * Huge page sizes with configured pools: 1073741824 The /proc/sys/vm/min_free_kbytes of 5417 is too small. To maximiuse efficiency of fragmentation avoidance, there should be at least one huge page free per zone in the system which minimally requires a min_free_kbytes value of 46137344 A /proc/sys/kernel/shmmax value of 6442450944 bytes may be sub-optimal. To maximise shared memory usage, this should be set to the size of the largest shared memory segment size you want to be able to use. Alternatively, set it to a size matching the maximum possible allocation size of all huge pages. This can be done automatically, using the --set-recommended-shmmax option. The recommended shmmax for your currently allocated huge pages is 5368709120 bytes. To make shmmax settings persistent, add the following line to /etc/sysctl.conf: kernel.shmmax = 5368709120 To make your hugetlb_shm_group settings persistent, add the following line to /etc/sysctl.conf: vm.hugetlb_shm_group = 78 Note: Permanent swap space should be preferred when dynamic huge page pools are used. seabios log: Thu Sep 7 19:53:37 CEST 2017 SeaBIOS (version 1.10.2-1.fc27) BUILD: gcc: (GCC) 7.0.1 20170211 (Red Hat Cross 7.0.1-0.2) binutils: version 2.27-6.fc26 No Xen hypervisor found.
