Hello,I'm having an issue running 32bit DomUs on my freshly installed debian bullseye xen 4.14 installation. I am unable to create any 32bit PV DomUs, I always get the following error:> xc: error: panic: xc_dom_boot.c:120: xc_dom_boot_mem_init: can't allocate low memory for domain: Out of memory > libxl: error: libxl_dom.c:593:libxl__build_dom: xc_dom_boot_mem_init failed: Operation not supported After examining the situation it turns out, that the capability for running 32bit PAE VMs apparently is not present: > host : toothless > release : 5.10.0-9-amd64 > version : #1 SMP Debian 5.10.70-1 (2021-09-30) > machine : x86_64 > nr_cpus : 4 > max_cpu_id : 3 > nr_nodes : 1 > cores_per_socket : 2 > threads_per_core : 2 > cpu_mhz : 2893.316> hw_caps : bfebfbff:76daf3bf:2c100800:00000021:00000001:000027ab:00000000:00000100 > virt_caps : pv hvm hap shadow > total_memory : 16299 > free_memory : 12010 > sharing_freed_memory : 0 > sharing_used_memory : 0 > outstanding_claims : 0 > free_cpus : 0 > xen_major : 4 > xen_minor : 14 > xen_extra : .3 > xen_version : 4.14.3> xen_caps : xen-3.0-x86_64 hvm-3.0-x86_32 hvm-3.0-x86_32p hvm-3.0-x86_64 xen_scheduler : credit2 > xen_pagesize : 4096 > platform_params : virt_start=0xffff800000000000> xen_changeset : xen_commandline : placeholder dom0_mem=1024M,max:1024M smt=true > cc_compiler : x86_64-linux-gnu-gcc (Debian 10.2.1-6) 10.2.1 20210110 > cc_compile_by : pkg-xen-devel > cc_compile_domain : lists.alioth.debian.org > cc_compile_date : Mon Sep 13 14:28:21 UTC 2021 > build_id : 1a67c53a8813b422d2033de494f8b444915791f2 > xend_config_format : 4 The capability "xen-3.0-x86_32p" is not listed under xen_caps.I think I am missing something rather emelentary, but am unable to figure out what - so any help would be greatly appreciated.
