error: internal error: libxenlight failed to create new domain 'sles12'


# cat /var/log/libvirt/libxl/sles12.log: libxl: debug: libxl_create.c:1362:do_domain_create: ao 0x7fae94005070: create: how=(nil) callback=(nil) poller=0x7fae940008c0 xc: error: xc_alloc_hypercall_buffer: mmap failed (11 = Resource temporarily unavailabl): Internal error libxl: error: libxl.c:570:libxl_list_domain: geting domain info list: Resource temporarily unavailable libxl: error: libxl.c:314:libxl__domain_rename: unexpected errorchecking for existing domain libxl: error: libxl_create.c:762:initiate_domain_create: cannot make domain: -5 libxl: debug: libxl_event.c:1591:libxl__ao_complete: ao 0x7fae94005070: complete, rc=-3 libxl: debug: libxl_create.c:1376:do_domain_create: ao 0x7fae94005070: inprogress: poller=0x7fae940008c0, flags=ic libxl: debug: libxl_event.c:1563:libxl__ao__destroy: ao 0x7fae94005070: destroy xc: debug: hypercall buffer: total allocations:17 total releases:16 xc: debug: hypercall buffer: current allocations:1 maximum allocations:3 xc: debug: hypercall buffer: cache current size:2 xc: debug: hypercall buffer: cache hits:14 misses:2 toobig:1

Resolution

As a workaround you can turn off apparmor chkconfig apparmor off and reboot the server.

Cause

The problem is due to a regression in the apparmor profiles for /usr/sbin/libvirtd. This regression prevents Xen from working properly.
