Package: xen-system-amd64
Version: 4.14.3-1~deb11u1
After applying the buster security update to xen, my VM won't start
any longer, complaining about a memory allocation error.
Switching back to the previous version 4.14.2+25-gb6a8c4f72d-2 lets
the VM start (again,) normally.
/var/log/libvirt/libxl/libxl-driver.log:
2021-09-21 14:01:44.645+0000: xc: panic: xc_dom_boot.c:120:
xc_dom_boot_mem_init: can't allocate low memory for domain: Out of
memory
2021-09-21 14:01:44.653+0000: libxl: libxl_dom.c:593:libxl__build_dom:
xc_dom_boot_mem_init failed: Die Operation wird nicht unterstützt
[means: the operation is not supported]
2021-09-21 14:01:44.662+0000: libxl:
libxl_create.c:1576:domcreate_rebuild_done: Domain 1:cannot (re-)build
domain: -3
The error is triggered, regardless if there was a boot-parameter
"dom0_mem=1024M:max=2048M" set or not.
/etc/xen/xl.conf was unaltered, i.e. 'autoballoon' was implicitely set
to "auto".
I am "on" Buster, kernel 5.10.0-8-amd64 (5.10.46-4), all relevant fixes
included.
Best regards,
