Hello there! I know, that it is "not so good practice", but anyway when I try to grow up dom0 memory with xm — I get following thing: node1 mva % xm list Name ID Mem VCPUs State Time(s) Domain-0 0 14287 8 r----- 255128.8 node1 mva % xm mem-set Domain-0 24G node1 mva % xm list Name ID Mem VCPUs State Time(s) Domain-0 0 13957 8 r----- 255131.4 node1 mva % xm mem-set Domain-0 24G node1 mva % xm list Name ID Mem VCPUs State Time(s) Domain-0 0 13626 8 r----- 255138.9 And it shrinks more and more every time. When I try to do it with xl — i get following: node1 ~mva % xl mem-set Domain-0 24g libxl: error: libxl.c:2125:libxl_set_memory_target cannot get memory info from /local/domain/0/memory/static-max : No such file or directory And, by the way, on another node I also have following issue: node1 ~mva % xl cpupool-list libxl: error: libxl.c:596:cpupool_info: failed to get info for cpupool1 : No such file or directory Name CPUs Sched Active Domain count Pool-0 12 credit y 13 And it is some more places where I get errors with xl. -- Best regards, mva _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org http://lists.xen.org/xen-devel

Uhm. It seems, it is 4.1.3 (as you can see from xl info) on 3.5.3-kernel
node, but I have all following issues even on 3.6.3-kernel node with 4.2.0.
P.S.:
By the way, I also has some network speed issues with domUs:
one_node ~mva % scp bkp.txz domU_on_another_node:/home/mva
bkp.txz
3% 592KB 259.7KB/s 0.0KB/s
01:12 ETA^CKilled by signal 2.
one_node ~mva % scp bkp.txz another_node_itself:/home/mva
bkp.txz
100% 19MB 3.8MB/s 6.2MB/s
00:05
almost the same for reversed process (downloading from that places)
it is rt8169 ethernet driver on "one_node", e1000e on
"another_node" and
I dunno which driver Xen uses for domUs, but:
domU ~mva % dmesg|grep -i ''Xen.*eth''
Initialising Xen virtual ethernet driver

I think you need to set an TSO (or maybe it is another flag) off on the guest''s adapter.
