Hi, when creating a bigger (> 50 GB) HVM guest with maxmem > memory we get softlockups from time to time. kernel: [ 802.084335] BUG: soft lockup - CPU#1 stuck for 22s! [xend:31351] I tracked this down to the call of xc_domain_set_pod_target() and further p2m_pod_set_mem_target(). Unfortunately I can this check only with xen-4.2.2 as I don''t have a machine with enough memory for

Hi all, I am using Xen 4.0.0 on top of Ubuntu Lucid (amd64), with the Jeremy kernel taken from git (xen/stable-2.6.32.x branch, 2.6.32.12 when I am writing this email). This kernel is also used in my domu. I can save a domu without any problem, but restoring it may need from 2 to 5 minutes, from a 1G checkpoint file (domu has 1GB RAM). There also errors in /var/log/xen/xend.log :

I tried booting the paravirt patches on a real machine to see what would happen. It had worked OK under qemu, so I thought it would be worth it. It seems to boot OK, though perhaps fairly slowly, but once it hits usermode it gets into trouble. When starting udevd, the startup script runs MAKEDEV, which seems to get stuck in an infinite loop in userspace. It eventually gets past that part
