Package: kvm Version: 72+dfsg-5~lenny1 Severity: normal
Live migration works fine, but when a guest has more than 1GB memory (e.g. -m 5120) live migration fails. The machine I try to migrate to complains migration: memory size mismatch: recv 1094725632 mine 5389692928 when I use -m 5120 (=5 GB). When using -m 10240 (so, 10GB) I get migration: memory size mismatch: recv 2168467456 mine 10758402048 Of course I use the same -m value option on both servers, so I'm really wondering why KVM reports a completely incorrect value for large memory guests. When using 2GB guests I don't get this message, but the migration also fails. For 1GB (or less) guests migration works flawless. -- Package-specific info: /proc/cpuinfo: processor : 0 vendor_id : AuthenticAMD cpu family : 16 model : 4 model name : Quad-Core AMD Opteron(tm)
