similar to: make clear a vmexit reason

Hi All, I am trying to provide services to guest VMs where I wish to run guest VMs in a loop. I wish to use a core to schedule a guest VM, service it eg. execute an ISR etc and then return to the context of Xen on that core, so that I can then schedule the next VM on that core. In doing all this, the goal is to avoid the calls to VMEntry and VMExit. Is there a workaround for this to be done or

Cleanup vmx vmexit handler. Current code doesn''t handle vmexits caused by triple fault, INIT, SIPI, etc, which are listed in IA32 Architecture System Programming Guide 2, Appendix I VMX Basic Exit Reasons, and calls __hvm_bug() when not handling such cases, actually domain crash should be good enough. Also various coding style cleanups. Signed-off-by: Xin Li <xin.b.li@intel.com>

This patch enables tracing VMEXIT/ENTRY for 64-bit systems (are there any 32-bit VT enabled systems out there?)

Hello I can''t seem to be able to get X working on domain U My setup domain0 -ubuntu breezy domainU -ubuntu breezy I tried 3 techniques 1. ssh -X domainU steps: on domain U $ export DISPLAY=:0 $ xhost + xhost: unable to open display ":0" on domain0 ssh -X domainU result: ssh conection established no X forwarding starts. after login tried

Hi all, I manage to create a VM (slackware image) and hide the PCI device (qlogic HBA) from Dom0 to DomainU. Now the Dom0 cant see this HBA and the ''xm list -l'' shows this pci device under the DomainU. But how can I do some scsi inquiry or check if this PCI device is visible to the DomainU from the DomainU''s console. Any help? Thanks and regards Ashit

Hi all, I have another problem with starting domainU (xenolinux). I took me pretty much quite some time and i can not figure out why starting a new domain is failing. I will really appreciate if somebody can help me with this error. The error I get when booting xen-domainU is: /======================= Red Hat nash version 4.1.18 starting Mounted /proc filesystem Mounting sysfs Creating /dev

Is there any particular reason why on 32-bits the order is VMLOAD then HVM_SAVE_ALL_NOSEGREGS, while on 64-bits its is the other way around? Trying to put in the saving of EAX, I could save a GET_CURRENT() on 32-bits if I could order things the same way as on 64-bits. Also, both versions seem to have a redundant GET_CURRENT() right after the clgi/sti sequence - again, is there a particular reason

Remove the do_nmi() call from the vmexit logic, as the NMI is held pending and will be handled in the context of the host when the STGI instruction is executed. This patch only modifies AMD-V code. This patch is required even without the other Xenoprofile patches applied. Applies cleanly to c/s 11831. Please apply to xen-unstable.hg regardless of the other patches. We also want these patches

Hello folks I see the EVTCHN driver being initialized as a part of DomainU. XEND (or domain controller) uses the EVTCHN driver to receive notifications for events on the control interface. However there is no XEND (or domain controller) that runs in DomainU. So what is the purpose of initializing EVTCHN driver in DomainU Thanks in advance Nauzad

Hi! I have a opteron machine running in 64bit mode. I would like to set up a Domain0 at 64bit and run 32bit domainU''s on top to use with other 32bit domains in regular x86 boxes for clustering.. Is this scenario possible, considering the use of Xen3 ? TIA -- Miguel Sousa Filipe _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com

The self_nmi() code cause''s an NMI to be triggered by sending an APIC message to the local processor. However, NMIs are blocked by the VMEXIT, until the next iret or VMENTER. Volume 3 Chapter 27 Section 1 of the Intel SDM states: An NMI causes subsequent NMIs to be blocked, but only after the VM exit completes. As a result, as soon as the VMENTER happens, an immediate VMEXIT happens

Hello all, I try to set a ntp server in domainU, but other vms cannot synchronizes with the ntpserver VM. When I choose to set ntp server in domain0, synchronization can be done. Why is that? I install xcp-xapi 1.5 on ubuntu server 12.04 64-bit. Many thanks! clayton claytonly _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org

I have a problem with SATA disk. Once, i start up my system (1 domain0 and 2 domainU on the same machine), it is good. But, where some of them have high traffic and thus require high disk usage i get this error in dom0''s dmesg: ATA: abnormal status 0xD0 on port 0x9F7 ATA: abnormal status 0xD0 on port 0x9F7 ATA: abnormal status 0xD0 on port 0x9F7 ata1: command 0x35 timeout, stat 0xd0

Hi, In the case of linux, crash_kexec() is occured by "sysrq c". In the case of DomainU on xen, Help is occured by "sysrq c" now. So The way of dumping DomainU''s memory manualy is nothing. I fix this issue by the following way. 1. Panic is occured by "sysrq c" on both Domain0 and DomainU. 2. On DomainU, coredump is generated in /var/xen/dump (on Domain0).

Hi list!: A question about the refinement of the configuration: Always when I start a domain kudzu (hardware detection daemon) ask me for remove hardware. I answer yes, but in the next boot kudzu ask again. I''m guessing that kudzu is asking for remove the «real» drivers that are inside the domU because the domainU was created copying the dom0 system in the domU. How can I deal with
