Hi all, I have the strangest issue here: I upgraded my Dell T300 system ("[i]server[/i]") from 8GiB to 16 GiB memory. When I boot snv 130 (and at least 127) with more than 8 GiB of installed memory outbound network traffic is impossible. [b]memory[/b] - 2 * 2 GiB Module - 2 * 2 GiB Module - 2 * 4 GiB Module [b]grub[/b] title snv_130 findroot (pool_rpool,0,a) bootfs rpool/ROOT/snv_130 kernel$ /boot/$ISADIR/xen.gz console=vga dom0_mem=4096M dom0_vcpus_pin=false watchdog=false module$ /platform/i86xpv/kernel/$ISADIR/unix /platform/i86xpv/kernel/$ISADIR/unix -B $ZFS-BOOTFS module$ /platform/i86pc/$ISADIR/boot_archive [b]network[/b] When I ping the [i]server[/i] the following happens: On the [i]server[/i] the arp entry for the [i]client[/i] is set. On the [i]client[/i] the arp entry for the [i]server[/i] is [b]never[/b] set. Networking between dom0 and domU and between dom0 and zones works. Networking between [i]client[/i] and domU/zones shows the errors described above. [b]tests[/b] I tried snv 130 and 127 (XVM). Both showed the same behavior: No network with 12 or 16 GiB, stable network with 8 GiB. snv 130 [i]without[/i] xvm works with 16 GiB of RAM installed. Swapping the memory modules does not alter the effect. Has anybody experienced this? What can I do to get it to work? Regards, Jens -- This message posted from opensolaris.org

What can I do to get it to work?No. What is the dom0 NIC? Have you tried snooping on the vnic to see what is moving through? I am guessing the NIC your using doesn''t support 64-bit DMA addresses and there isn''t enough low memory in dom0? MRJ
Hi mrj, thank you for your quick reply.> What about client dom0?This is (was, see below) the problem: all communication ways ''leaving'' the server were somehow blocked. I "kind-of-solved" the problem by partitioning the available memory: title snv_130 XEN, 16 GiB RAM findroot (pool_rpool,0,a) bootfs rpool/ROOT/snv_130 kernel$ /boot/$ISADIR/xen.gz console=vga dom0_mem=8G mem=16G dom0_vcpus_pin=false watchdog=false module$ /platform/i86xpv/kernel/$ISADIR/unix /platform/i86xpv/kernel/$ISADIR/unix -B $ZFS-BOOTFS module$ /platform/i86pc/$ISADIR/boot_archive That is 8GB dom0 and 8GB for Xen. This did the trick and I have network again. Jens -- This message posted from opensolaris.org
