sorry for the delay... was sleep time :)
i want to reiterate that the HOST is downgraded and running the .42 QEMU code... just to make sure we're on the same page... everything i'm reporting and looking at is on the HOST... here's one paragraph from /proc/cpuinfo as requested... ----->8 snip 8<----- processor : 0 vendor_id : AuthenticAMD cpu family : 21 model : 2 model name : AMD FX(tm)-8350 Eight-Core Processor stepping : 0 microcode : 0x6000822 cpu MHz : 1400.000 cache size : 2048 KB physical id : 0 siblings : 8 core id : 0 cpu cores : 4 apicid : 16 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 13 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt pdpe1gb rdtscp lm constant_tsc rep_good nopl nonstop_tsc extd_apicid aperfmperf pni pclmulqdq monitor ssse3 fma cx16 sse4_1 sse4_2 popcnt aes xsave avx f16c lahf_lm cmp_legacy svm extapic cr8_legacy abm sse4a misalignsse 3dnowprefetch osvw ibs xop skinit wdt lwp fma4 tce nodeid_msr tbm topoext perfctr_core perfctr_nb arat cpb hw_pstate ssbd ls_cfg_ssbd retpoline retpoline_amd npt lbrv svm_lock nrip_save tsc_scale vmcb_clean flushbyasid decodeassists pausefilter pfthreshold vmmcall bmi1 bogomips : 8036.20 TLB size : 1536 4K pages clflush size : 64 cache_alignment : 64 address sizes : 48 bits physical, 48 bits virtual power management: ts ttp tm 100mhzsteps hwpstate cpb eff_freq_ro ----->8 snip 8<----- dmidecode is here: https://pastebin.com/LQZLmQ1g i do not see any DENIED or AppArmour related messages in dmesg... at least not via various grep searches... i don't see any entries in /var/log/libvirt that i can tell are relevent... i have a log for a copy of one of the 64bit VMs and the only thing that i can see that might indicate it was panicked is the "signal 15" terminations where i had to "Force Stop" the VM... that guest was created for troubleshooting... it only had the CPU section removed and the video changed to Cirrus... it uses the original guest's img... here's that log: https://pastebin.com/cs1i6s7B for the kernel request... both were upgraded at the same time...
