Was using qubes when I got auto-logged out. A while after logging back in I found several lines in dom0 dmesg that said “maptrack limit reached, can’t map all guest pages”.
Linux kernel source shows:
case GNTST_no_device_space: pr_warn_ratelimited("maptrack limit reached, can't map all guest pages\n"); break;
Does this mean I ran too many VMs and exceeded my system memory?
Or maybe it means that I used too much memory in dom0 and need to raise it above 8 gigs for dom0?
Any ideas are appreciated.
