I set up a domU as a backup server, but it has very, very poor network performance with external computers. I ran some tests with iperf and found some very weird results.

Hello, I thinking about using PCI passthrough to dedicated a domU as firewall. I understand PCI passthrough concept. When done, my domU will see network card and the dom0 won''t any more. So I''ll be able to filter all trafic from outside, since it will go through network domU. Then, how will I be able to connect other domU (and maybe dom0) to t...

Just reporting some iperf results. In each case, Dom0 is iperf server, DomU is iperf client: (1) Dom0: Intel Core2 3.16 GHz, CentOS 5.2, xen 3.0.3.

I am attempting to setup a firewall in a DomU. The firewall program I eventually want to run is Shorewall. Both my Dom0 and DomU are Debian Lenny 64 bit systems. The Dom0 has four physical network interfaces installed. Currently, one of the NICs is hidden using the pciback.hide command in the /boot/grub/menu.lst file. Similarly, the hidd...

Hello! Can i get uuid of DomU from this DomU ? What is needed? Thanks. _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hi, dom0: Debian Lenny 2.6.26-2-xen-amd64, domU: same. Xen 3.2-1 After resizing a LV on dom0, Xen is not reporting the new extended size to the PV domU even though dom0 is well aware of the new size. I''ve rebooted domU (not dom0 yet as that''s running a lot of other domU''s). The LV I tried to resize is encrypted. Resiz...

Hello. I''m trying to use vlan in domU, but have something strange: I created bridge on eth0. This interface was configured as trunk with vlan 300, 301. I use this bridge in my domU, and I can see tagged packets when run tcpdump in domU. Also I created interface on domU to work with vlan 300. On this interface I see untagged packets...

I have a sles10 domU running on a sles11 dom0. xen is version 3.4. We''re trying to pass through a scsi card to the domU. We assign the domU the scsi card through virt manager. When we try to boot the domU it won''t boot. We need to update fstab and menu.lst, but we need to boot with the hardware attach...

Hi all, I''m a newbie on this list. I''m using xen 3.0.3 on CentOS50. I installed a new flavor of kernel in a domU via a standard RPM, which modified my grub.conf by adding a new entry to boot on the new kernel. When rebooting the domU by pygrub, I didn''t see the new grub entry. I tried to restart xend, with no effect. By googling a little, I understood that kernel files used by a domU must be pres...

Hi, I''m trying to setup xen on a server with bridge networking. I have RedHat as my dom0. I have two Ubuntu instances and one CentOS instance as domU''s. All of them (dom0 and domU) use static ip addresses. The configuration files for domU''s specify in the vif line what ip address to be assigned to that particular domU. It works fine for my ubuntu domU''s. But it does not work for my CentOS domU. Can someone help me fi...

Hi, I have been doing some diskIO bench-marking of dom0 and domU (HVM). I ran into an issue where domU performed better than dom0. So I ran few experiments to check if it is just diskIO performance. I have an archlinux (kernel 3.5.0) + xen 4.2.2) installed on a Intel Core i7 Q720 machine. I have also installed archlinux (kernel 3.5.0) in domU running on this m...

...PCI -passthrough support. Please correct me if I am wrong in my following inferences. 1. Device emulation and pass through are both implemented using split drivers. 2. But, in case of emulation drivers of dom0 are used where as in case of passthrough ( as the name suggests ) native drivers in domU are used . 3. dom0 provides a virtual PCI device { an interface for device-OPs and status of this virtual device} to domU and through associated event channel domU makes "synchronous" use of this device. === Queries: 1. What i am really not so sure about is ... passthrough case...

Is there a way for a domU to discover size changes of block devices modified by dom0? To make it clear - if I do in dom0 a lvresize of a logical volume given as physical disk to a domU, is there a way to use the new size of this device within the domU without reboot? Thanks Ralf _________________________________________...

Hello, After a few of us have spent a week google''ing around for answers, I feel compelled to ask this question: how do I stop packet loss between my dom0 and domU? We are currently running a xen-3.3.0 (and have tried with xen-3.2.1) on a Gentoo system with 2.6.18 kernel for both domU and dom0. We have also tried a 2.6.25 kernel for dom0 with exactly the same results. The goal is to run our multicast processing application in a domU with the BRIDGED config...

Hi all, where can I set the date in domU. ''ntpdate -u ...'' works but dosn''t set the date. date MMDDhhmm has also no effect.

Setup: RedHat/Centos/Sci. Linux 5 update 3, Dom0: kernel-xen-2.6.18-164.10.1.el5xen 64-bit (on Dell Poweredge 2950 dual quad-core). DomU: kernel-xen-2.6.18-164.10.1.el5xen 32-bit, 1 vcpu 6 domU''s per dom0. We have also seen the same problem with 2.6.18-164.9.1 and 2.6.18-164.6.1 kernels on this branch. Symptom: On 32-bit domU only (we have never seen 64-bit domU be affected), we observe that the clock gets set forward by...

...set up a PVM on xen-3.3.1 debian-amd64. I need advices about the best methods to install a fresh debian on it (i.e. how to choose the kernel for pvm) . I''ve installed xen from sources and only have one xen kernel in /boot which I''m using for dom0; should I use the same kernel for domUs? There is any problem on use vcpus=2; the other vm is an hvm running winxp and I would like to know if using 1 or 2 vcpus on the new pvm will slowdown the hvm. Any help would be appreciated. regards, -- edu _______________________________________________ Xen-users mailing list Xen-users@lists....
