I'm running CentOS 5.1 with all updates, and the xen kernel. For some reason the OS is not seeing the full amount of ram. #uname -a Linux CentOS-VM-A 2.6.18-53.1.21.el5xen #1 SMP Tue May 20 10:03:27 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux # free total used free shared buffers cached Mem: 6104064 3445136 2658928 0 1412236

It seems that VCPU system time isn''t monotonic (using 3.0.4). It seems it might be correlated to when a VCPU is switched across real CPUs but I haven''t conclusively proved that. But e.g.: { old = { time = { version = 0x4ec pad0 = 0xe8e0 tsc_timestamp = 0x22cc8398b7194 system_time =

Hi Konrad, I just tried to boot a 3.8.0-rc0 kernel (last commit: 7313264b899bbf3988841296265a6e0e8a7b6521) as dom0 on my machine with current xen-unstable.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi list, I have an IBM xseries 345, running CentOS 5.3, hosting a few Xen domUs. However, I need more RAM -- but cannot remember if all (four) RAM sockets are populated (which would mean to buy higher capacity modules) or if there are two slots left to use. However, I'd like (and think that it's possible, but don't remember how) to

I'm recording TCP network throughput performance between Dom0 IP stack and all my guest domains (currently 6 running simultaneously). All guests are running simultaneously, but I only ever transmit between Dom0 and one of the DomUs while the other five are idle. When running a netperf TCP_STREAM test (netperf on Dom0, netserver on DomU) I record the following performance numbers, CPU % as

I am unable to boot Dom0 on my IBM eServer BladeCenter HS20, type 8843, EMT64 blades. I have read reports that Dom0 boots on Opteron boxes, but on my EMT64 blades, it does not.

Hi Folks: I run into a problem when enabling Xen in next generation server platforms with Xen c/s is 21380. Xen reported "CPU Not responding" when booting up 32 CPUs( 2 sockets with 8 cores/16threads total). The log files belonging showed something wrong with APCI. So I added x2apic=0 in the xen grub line, but the symptom remained. However, Native RHEL5.5 can

I''ve had domU''s hickup a few times with latest unstable, and I guess this can be expected. Is there a procedure in place to report these problems?

Adding apic_verbosity=debug gives me that (hope nothing miss-typed as I have no serial console on this box).

Hi! We have a problem that the dom0 very often does not boot and hangs in the hypervisor - see screenshot. The last message is: (XEN) Dom0 has maximum 16 VCPUs (afterwards xen should overwrite the memory) We are using the xen kernel from kernel.org git. Kernel is 2.6.32.24-xen with Xen 4.0.1 Hardware is HP DL380. Is this a known problem? Any hints what could be the problem and how we can
