similar to: panic in e100_exec_cb()

Some users are hitting this panic in network_alloc_rx_buffers() when running a big network intensive app: /* Check return status of HYPERVISOR_dom_mem_op(). */ if ( rx_mcl[nr_pfns].args[5] != nr_pfns ) panic("Unable to reduce memory reservation\n"); I''m not clear on what is happening here. Are the domains changing size? Which memory reservation is being

Hi, > Can you manually do on the xen interfaces what the scripts would? How about > doing it on some other interface configured in a similar way? Toying with the vif-route script, I might have found a workaround for this issue. If I disable the ifconfig and ip route commands from vif-route script, and bring up vif interface by hand later on, everything seems to work. In other works,

Hi, I have set up an ubuntu edgy guest domain on a fiesty host domain. The installation was successful but on running xm create -c baseimage, I get the following error message: Error: (22, ''Invalid argument'') The problem seems very similar to the one here: http://lists.xensource.com/archives/html/xen-users/2007-07/msg00361.html but I''m not able to figure out what the

With GPLPV under 2.6.30, GPLPV gets the following from the ring: ring slot n (first buffer): status (length) = 54 bytes offset = 0 flags = NETRXF_extra_info (possibly csum too but not relevant) ring slot n + 1 (extra info) gso.size (mss) = 1460 Because NETRXF_extra_info is not set, that''s all I get for that packet. In the IP header though, the total length is 1544 (which in itself

Hi guys! I installed XEN 4.0 on Debian Squeeze but I cannot get the first DomU (not an image) started. Attached you will find /etc/xen/xen1.conf and the result of "xm create -c /etc/xen/xen1.conf" in xen1.log. Can you help me? What did I wrong? Is it about the fstab in xen1 (see also attached)? Many thanks in advance! Regards Stefan

Hi All, I am adding the patch mentioned here http://lists.xen.org/archives/html/xen-changelog/2013-02/msg00235.html I am getting errors on compiling Xen tools. My /tools/include/xen-foreign/mkheader.py looks different from the one that is mentioned in the above link, which I feel is due to version difference. I am using Xen 4.3.3 version. My understanding is that due to this version difference I

Hi folks, Host - Debian Etch Guests - Debian Etch. Performed following steps to create duplicate guest, a mail server. 1) # cp /etc/xen/guest-1.cfg /etc/xen/guest-2.cfg edit guest-2.cfg changing the settings of:- disk = [''file:/vserver/domains/guest-2_directory/disk.img,hda1,w'', ''file:/vserver/domains/guest-2_directory/swap.img,hda2,w''] # Hostname name

Hi. First of all, thanks for Xen. It''s terrific! I''m interested in doing memory oversubscription and am wondering if Xen can do this (now or in the future). For example, on a machine with 100MB available physical memory, can I: 1. Create a domain with a 90MB allocation 2. Inflate a balloon in that domain and return say 40MB back to Xen I know there are mechanisms for doing

Hi, I install a guest Fedora inside the host Fedora. When I use the service xend status to check the status of xend. It shows xend is running. However when I use xm create xen1 to start the guest domain xen1, it failed. The corresponding file xen1 is in /etc/xen/xen1. The error msg is as follows: [root@phillis xen]# xm create xen1 Using config file "./xen1". Going to boot Fedora

Posted this to xen-users back in Oct (http://www.gossamer-threads.com/lists/xen/users/186768), but just confirmed that I''m still seeing this behavior on 4.1. Polling the UCE-SNMP-MIB::ssCpuRawIdle counter results in a total that''s double the actual number of cpu''s on the system, so for example: nms ~ # snmpwalk -v 2c -c ''XXX'' xen1

Hey everyone, Thanks for the quick help resonses once again, We got some mail saying that RAM disks were not the way to go. So we re-installed, made several partitions to use, and rebuilt xen. However, we''re still having trouble mounting partitions when xeno-linux boots. We give a physical grant of one of our newly made paritions (/dev/hda14 in particular) to the domain. But when

I''m getting the error: xend (12, ''Cannot allocate memory'') From the command line after the Dom-0 goes through a period of heavy memory usage. I don''t have any hard numbers on how to duplicate it, but I''ll give you the steps I''ve gone through to duplicate the problem. First, some information about my setup. It''s a new setup, and has

Hi all, I''m stuck with a peculiar problem. I have CentOS 5.5 and Xen. I have numerous Windows 2003 guests and never had this problem. An application requires SQL server 2008 which is requiring Windows Server 2008. I downloaded the 2.8 Gig install DVD ISO. I create a new guest and connect the ISO as hdc. The system starts and says "Starting Windows" but hangs and no

Hi all, we are running CentOS 5.2 Xen virtualization system with the latest CentOS packages with couple of VMs on DELL PowerEdge. &quot;Sometimes&quot; the whole machine freezes without anything in log files, anything on the console. &quot;Sometimes&quot; really means we cannot define why or when. Sometimes the machine was idle with just one VM, sometimes quite busy with couple of
