Since you suspect a problem in the host with migration, we'd need to have the corresponding host logs, including the libvirt logs, and if this is a production server, my suggestion would be to refile this as a SLES 12SP5 issue. But for what I see here, the guest encounters a general protection fault in "make_kuid" during "filename_lookup", in a low memory condition with OOMed processes. I don't see for now an indication that something went wrong with the migration. 2022-08-18T10:31:31.125351+00:00 pontifex2 kernel: [ 5236.588301][T25754] general protection fault, probably for non-canonical address 0xb110bc3ba3d49fbc: 0000 [#12] PREEMPT SMP NOPTI 2022-08-18T10:31:31.125398+00:00 pontifex2 kernel: [ 5236.591945][T25754] CPU: 5 PID: 25754 Comm: rsyncd Tainted: G D 5.14.21-150400.24.18-default #1 SLE15-SP4 695ab7a8fc20f5ddb345280570966cd1eb06d469 2022-08-18T10:31:31.125409+00:00 pontifex2 kernel: [ 5236.596511][T25754] Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS rel-1.12.0-0-ga698c89-rebuilt.suse.com 04/01/2014 2022-08-18T10:31:31.125412+00:00 pontifex2 kernel: [ 5236.600209][T25754] RIP: 0010:__d_lookup_rcu+0x67/0x190 2022-08-18T10:31:31.125415+00:00 pontifex2 kernel: [ 5236.601560][T25754] Code: e8 49 c1 e9 20 48 8d 04 c2 45 89 ce 41 83 e6 07 48 8b 18 48 83 e3 fe 75 11 e9 92 00 00 00 48 8b 1b 48 85 db 0f 84 86 00 00 00 <8b> 6b fc 4c 3b 63 10 75 eb 48 83 7b 08 00 74 e4 83 e5 fe 41 f6 04 2022-08-18T10:31:31.125417+00:00 pontifex2 kernel: [ 5236.607438][T25754] RSP: 0018:ffffb6dc8c657ae0 EFLAGS: 00010286 2022-08-18T10:31:31.125418+00:00 pontifex2 kernel: [ 5236.609482][T25754] RAX: ffff8bc91c95dd50 RBX: b110bc3ba3d49fc0 RCX: 0000000000000009 2022-08-18T10:31:31.125420+00:00 pontifex2 kernel: [ 5236.612927][T25754] RDX: ffff8bc91b680000 RSI: ffffb6dc8c657c20 RDI: ffff8bb59caf7d40 2022-08-18T10:31:31.125422+00:00 pontifex2 kernel: [ 5236.615312][T25754] RBP: 00000000d410fd7a R08: ffffb6dc8c657c20 R09: 0000000000000038 2022-08-18T10:31:31.125423+00:00 pontifex2 kernel: [ 5236.617599][T25754] R10: ffff8bb24603a050 R11: 0000003800000000 R12: ffff8bb59caf7d40 2022-08-18T10:31:31.125427+00:00 pontifex2 kernel: [ 5236.624006][T25754] R13: 000000384b7755c2 R14: 0000000000000000 R15: ffffb6dc8c657d50 2022-08-18T10:31:31.125428+00:00 pontifex2 kernel: [ 5236.627676][T25754] FS: 00007fa500e97740(0000) GS:ffff8bc91fb40000(0000) knlGS:0000000000000000 2022-08-18T10:31:31.125430+00:00 pontifex2 kernel: [ 5236.629963][T25754] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 2022-08-18T10:31:31.125431+00:00 pontifex2 kernel: [ 5236.631707][T25754] CR2: 0000556e9bb18fd0 CR3: 00000001cee98000 CR4: 00000000000406e0 2022-08-18T10:31:31.125433+00:00 pontifex2 kernel: [ 5236.633849][T25754] Call Trace: 2022-08-18T10:31:31.125435+00:00 pontifex2 kernel: [ 5236.634763][T25754] <TASK> 2022-08-18T10:31:31.125436+00:00 pontifex2 kernel: [ 5236.635767][T25754] ?
