Created attachment 427367 [details] xend.log Description of problem: When trying to balloon up RHEL 6 PV guest to a larger memory size, the guest just stays in the memory size with which it is created. Version-Release number of selected component (if applicable): kernel-xen-devel-2.6.18-194.3.1.el5 xen-libs-3.0.3-113.el5 xen-debuginfo-3.0.3-113.el5 xen-devel-3.0.3-113.el5 kernel-xen-2.6.18-194.3.1.el5 xen-3.0.3-113.el5 How reproducible: Always Steps to Reproduce: 1. # xm li Name ID Mem(MiB) VCPUs State Time(s) Domain-0 0 1024 4 r----- 18081.7 vm1 56 512 4 -b---- 1.0 2. # xm info | grep mem total_memory : 4029 free_memory : 2385 3. # xm li -l 56 | grep mem (memory 512) (shadow_memory 0) (maxmem 1024) 4. # xm mem-set 56 800 5. # xm li -l 56 | grep mem (memory 800) (shadow_memory 0) (maxmem 1024) 6. # xm li Name ID Mem(MiB) VCPUs State Time(s) Domain-0 0 1024 4 r----- 18086.4 vm1 56 512 4 -b---- 7.3 Within the guest, memory size is reported as 490M. 7. # xm info | grep mem total_memory : 4029 free_memory : 2385 Actual results: RHEL 6 PV guest cannot be ballooned beyond the memory size with which it is created. Expected results: Guest could be ballooned to any memory size below maxmem as along as there are enough free memory. Additional info: BTW, within RHEL 6 PV guest, directory of /proc/xen/ is empty which makes it difficult for us to get information of PV guest. Is it expected?
